Electricity demand in Japan is widespread for household appliances such as refrigerators, microwave ovens, cooking equipment, washing machines, air conditioners, televisions, audio equipment, personal computers, game machines, and offices such as companies and organizations Has office automation equipment such as personal computers, copiers, facsimiles, and printers, and air-conditioning equipment, and stores have lighting equipment and exhibits, and many electronic and electrical equipment are installed in nearby facilities and areas. Electricity consumption is increasing year by year. Furthermore, the load factor, which is the ratio between the peak power consumption and the average power consumption, is getting worse year by year. The deterioration of the load factor has the problem that the electric power company needs to maintain the power generation equipment to cope with the peak power, and the power generation equipment cannot be operated efficiently. Moreover, since thermal power generation that is easy to start and stop is mainly used as a power generation facility that responds to load fluctuations, it is preferable from an environmental standpoint, such as a large amount of CO2 emission compared to the average of all power. However, various studies and efforts are being made to promote load leveling.
In addition, with the recent increase in environmental awareness, the introduction of power generation facilities such as power generation systems and fuel cells using natural energy with a low environmental load is being promoted worldwide. At present, the introduction of these power generation facilities is being promoted by being subsidized in whole or in part by subsidies supported by each country. In the future, along with the popularization of these power generation facilities, power generation facilities with storage facilities are also expected to become popular.

  Patent Document 1 discloses a system that includes a power storage facility, purchases power at a low price, and sells power at a high price. Patent Document 1 discloses a purchase decision-making device that determines an optimal power purchase amount and purchase time according to a predetermined purchase rule based on price fluctuation information of a power price, a power storage device that stores the purchased power, and a price of the power price. A system that includes a sales decision-making device that determines the optimal sales volume and timing of stored electricity according to predetermined sales rules based on fluctuation information, and an electronic payment device that uses electronic payment to exchange money associated with power trading is there.

  A trading method and trading system for carbon dioxide emission rights are disclosed in Patent Document 2. In Patent Document 2, when the actual carbon dioxide emission amount is larger than the carbon dioxide emission rights acquired by the entity, the center instructs the entity to obtain the carbon dioxide emission rights corresponding to the excess amount. On the other hand, when another entity performs solar power generation, the center grants the carbon dioxide emission right according to the amount of power generation to the entity. Both of these carbon dioxide emission rights are traded on the Internet, and the selling price of the carbon dioxide emission rights is determined at the center or by a floating exchange rate system.

  Patent Document 1 is a system that obtains profits by storing relatively low-priced late-night power and selling power in the daytime when the price is relatively high, but stores the power in a power storage facility and consumes the power. In addition to the economic value that can be obtained by this, it is not a system that gives value by evaluating the value of environmental contributions. Patent Document 2 is an invention relating to a carbon dioxide emission right trading method, which trades carbon dioxide emission rights by solar power generation, is equipped with a power storage facility, and gives value by evaluating its contribution to the environment. Not a system.

  In general, power storage devices for power storage are not widely used because of their high installation costs and maintenance costs. Despite the problem of load factor deterioration in Japan as described above, grasp and evaluate the value of the power usage mode that power storage facilities and power generation facilities affect the load factor reduction. Since there is no system and it is impossible to actually classify the type of power, the current situation is that only the price difference is set in the power rate by the power menu according to the time zone like the midnight power menu. Under such circumstances, the storage equipment owner can only get its economic profit by the difference between the price of nighttime power and the price of daytime power set by the power purchase menu, so that the economic profit is sufficient. It is thought that one of the reasons that the spread is hindered in many cases is not obtained.

In addition, power generation facilities with low environmental impact are expected to become more widespread in the future, but the power generation costs including the introduction costs are still at the same level as the power generation costs of electric power companies that generate power with large power generation facilities. Has not reached. At present, the difference is covered by subsidies received from the national and local governments, fee menus with favorable conditions provided by electric power companies, or the burden of individuals with high environmental awareness.
In particular, an environment in which a user who has a small-scale power storage facility for home use can reduce the carbon dioxide generated during power generation by storing power at midnight and using it in the daytime to level the load There is no means to evaluate the contribution to the environment by contributing to the load leveling of a large power plant by making a contribution or self-consuming the power generated by a small-scale power generation facility. Moreover, since the absolute amount of the contribution is small individually, there is no system to collect even if there is a third party who wants to acquire the value, and it was impossible to distribute the value. For example, trading (buying and selling) cannot be performed as a value such as carbon dioxide emission rights.
On the other hand, there is a demand for users not only to contribute to the environment but also to recover the investment required for installation as soon as possible. Therefore, in order to aim at the full-scale popularization of a power storage system for storing power and a power storage system combined with a power generation system with a small environmental load, it is necessary to satisfy such user requirements.

In the present invention, the “storage facility” means a storage battery such as a secondary battery such as a lead storage battery, a nickel metal hydride battery, or a lithium ion battery, or an electric double layer capacitor, and charging / discharging the storage element to obtain power information. A facility with a configuration to generate. Alternatively, it may be a power storage device in which water is electrolyzed and hydrogen is stored, and hydrogen is supplied to the fuel cell as needed to extract electric power. The “power generation facility with a small environmental load” typically includes a solar power generation device, a wind power generation device, a micro hydropower generation device, a fuel cell, a power generation by a gas engine, and the like.
These power storage equipment and power generation equipment are installed for each building such as a detached house, condominium, building, etc., or installed in traffic lights, public facilities, street lamps on public roads, and the like. There are no limitations on the scale of power storage equipment and power generation equipment, but it is possible to conduct transactions alone if the equipment is large. In the present invention, not only large-scale equipment but also small systems that are difficult to trade by themselves, or when large-scale equipment and small-scale equipment are mixed, enable transactions by collecting them.

  A small system is a facility that is used by ordinary households, small businesses, various organizations, and the like. In the case of a power storage facility, the scale is about 100 kWh or less, more preferably 50 kWh or less, and about 0.5 kWh or more. In the case of a power generation facility, the power generation facility is 20 kW or less, more preferably 10 kWh or less, and 0.5 kWh or more. In the state where these power storage facilities or power generation facilities are connected by a network of a plurality of units and are connected on a scale of several thousand units or more, the present invention can be used effectively. Alternatively, small-scale transactions such as Internet auctions can be enabled.

  In the present invention, the management server is a computer installed in a company or a trader that aggregates the power information of the power storage facility and the power generation facility and mediates between the provider of the power information and the person who wants to acquire value. . In the present invention, the power storage system having the power storage facility or the power generation facility, the value acquisition applicant, and the management server are connected via a network such as the Internet or a dedicated line. In the present invention, the consideration is determined based on the power information in the management server, for example. As a factor for determining the consideration, the time when the power is stored in the power storage facility, the type of power used for power storage, and the like are used. There are types of power generation, for example, information that distinguishes between hydropower, thermal power, and nuclear power generation, as well as information that distinguishes the location conditions of power generation facilities, the distance to the power plant, and the time zone when power was generated. Can be mentioned.

In the present invention, “value” has the following meaning. For example, with respect to power storage, it stores the midnight power, when using the power stored power to large daytime power demand (large time zone of the power demand does not use power lines), power usage Value due to time shift and value that contributes to reducing the load factor on the power system are generated, and consideration is determined for this value. As another example, when the electric power generated in the morning with solar cells is stored until the daytime hours when power demand is large and used during the daytime hours, the power generated by solar power generation The value that it has and the value that contributes to reducing the load on the power system in the daytime are generated. In other words, by combining power generation equipment and power storage equipment, it is possible to add the above-mentioned environmental contribution and value of load reduction to the value of power consumption obtained by solar power generation, which had a conventional value. And value can be increased.

In the present invention, “consideration information” refers to power consumption by storing power purchased from an electric power company in a power storage facility, or power stored in the power storage facility or power generated by a power generation facility owned by itself. It does not mean a price for self-consumption, and the power storage system of the present invention stores midnight power, or stores power from a power generation facility, and consumes the power stored in the daytime, thereby shifting the time of power usage. Or, it means the information given to the value set for the power generated by the power generation equipment with a small environmental load or the consumption category distinguished by the consumption form of the generated power, and is the value information for the environmental contribution introduced for the first time in this invention. is there. More specifically, for example, power time-shifted by the power storage system contributes to load leveling of daytime power and nighttime power, so the value for the contribution and power time-shifted by the power storage system are Since the environment is improved by reducing carbon dioxide emissions in the case of thermal power generation, the value for the degree of environmental improvement can be considered. The magnitude of the value can be determined by managing the power information and determining the price based on the power information and the price information, thereby specifying the value corresponding to the degree of contribution. Accordingly, the power information means data such as the degree of environmental contribution information, carbon dioxide reduction contribution information, power generation cost reduction cost information, etc. as data relating to the value of power for determining the value. The price can be determined based on the power information transmitted from the power storage system and the price information . That is, the data is used for conversion (processing) by four arithmetic operations or the like in order to determine the price based on the power information and the price information .

Moreover, the electrical storage equipment management system of this invention can determine consideration according to the consumption form (consumption classification information). It becomes possible to promote load leveling by deciding the consideration for the value of environmental contribution by consumption form (consumption classification information) .
The “consumption classification information” in the present invention means that it is unnecessary for the minimum life because it is consumed by equipment (for example, a refrigerator) necessary for normal life even when power is consumed by the equipment in its own building. This is information set so that it can be distinguished from consumption by facilities (amusement facilities, games) that would have been able to be saved if they were confused . If consumption categories can be set in this way, it may be possible to set different considerations between them. Further, even when it is difficult to set them finely, it is conceivable to set weights for the power consumption in several stages and set a price for each.

In addition, it is conceivable that there is a difference in consideration depending on the contents of the contract between the owner (contractor) of the power storage facility or power generation facility and the provider of this management system, the value acquisition applicant, or the power company. Information on contract contents may be included in the power contract information to be managed. For example, in a power storage facility provided with a power generation facility, information such as a power sale contract period, a power sale time zone, and a maximum power consumption amount may be included in the power sale contract. In addition, information on the contents of these contracts is included in the power contract information so that the consideration can be distinguished according to the contract contents such as the presence or absence of power supply to neighboring facilities, the method of setting value for power and the settlement method, and the type of agent. May be.
As described above, the present invention stores power at midnight by a power storage system, or stores power from a power generation facility and consumes power stored in the daytime, thereby shifting the time of power use or generating power with a small environmental load. The value set for each of the consumption categories distinguished by the power generated by the facility or the consumption form of the generated power is quantified value, and the value is determined based on the value information and power information. The consideration information constitutes a condition for obtaining the consideration . Considerations determined based on the consideration information include not only money but also goods, cash vouchers, contribution points, and the like. The consideration information is given in a format that indicates a condition of consideration (also referred to as a value acquisition condition). For example, if the consideration information is set, if the condition “A” is satisfied for power consumption, “ This is data obtained by quantifying or symbolizing information such as giving a product (consideration) “B” free of charge. Specific examples will be described in the examples described later. The article may be a hobby / preference item or a rare value product such as a garden chair, a pesticide-free vegetable set, a domestic airline ticket, a theater appreciation ticket, or a premier admission ticket.

This value may be operated at a fixed price with an absolute standard, and the demand between the contractor who provides the value and the value acquisition desirer who wants to acquire the value. It may be a system in which the price is determined so as to fluctuate depending on the supply relationship.
In addition, when determining a certain price for the power information, it adds to the power information by charging / discharging generated during a certain period on the power storage facility side and the power generation facility side, and sends them to the management server with information for distinguishing them, Although it may be accumulated by the management server, the power information by charging / discharging may be accumulated on the power storage facility side or the power generation facility side, and sent to the management server every time it exceeds a certain amount. The data transmission method may be automatic transmission, or may be a form in which a user reads a numerical value displayed on the display unit of the power storage facility or the power generation facility and transmits it using a terminal.

In the present invention, the value acquisition applicant is a person who provides consideration for the value generated by the power storage system, such as a manufacturer of a storage battery and a manufacturer of a solar battery, a wind power generator, a micro hydroelectric generator, a fuel cell, a gas engine, It means an environmental improvement promotion organization, a public organization, a company, a charitable organization, a power company, or a person who wishes to purchase carbon dioxide emission rights (a company).
Disclosure information means, for example, power information and power value data of a contractor, acquisition consideration information of a value acquisition applicant, and the like, and is information disclosed to users of the system of the present invention via the network 300. .

Any transmission procedure (protocol) or communication network between the power generation facility and the management server can be used, and is not limited to a specific one. However, an appropriate one should be selected between the power generation facility and the management server with sufficient consideration of communication compatibility, confidentiality, speed, and the like.
Further, there is a means for appropriately classifying the electric power generated by the contractor shifting the power consumption time or the generated electric power in the facility and integrating the amount of electric power, and the contractor (not owning the facility) who wants to acquire value. You may make it have a means to accumulate | store the usage-amount of the electric power consumed in the business activity, and a means to compare and offset the said electric power consumption and usage-amount.

Hereinafter, the present invention will be described in detail based on examples. In addition, this invention is not limited by this.

The communication interface 124 is a part that performs connection control and data transmission / reception with respect to the network 300. The power conditioner 120 manages power storage information and charge information indicating the power storage state of the power storage facility 110 and discharge information to the load, and generates power information. That is, the control unit 125 controls the current direction of the DC / AC inverter unit 122, acquires information on the power and time, and stores the charging time, discharging time, and power amount of the power storage equipment 110 in the data storage unit 126. Store as charge / discharge information. Further, the time when the power of the power storage facility 110 is supplied to the user load 150, the amount of power, and the like are stored as power consumption information. The stored information is transmitted to the management server 400 via the network 300 by the communication interface 124 as power information of the power storage system.

  The opening / closing unit 140 is connected to the DC / AC inverter unit 122, the watt-hour meter 160, and the user load 150, and the user load 150 supplies either one of the power extracted from the power storage facility 110 and the commercial power supplied from the power company. Switching operation to supply to In the case where the power storage facility 110 is sufficiently charged, power is supplied from the power storage facility, and it is preferable that power be supplied from the power company during a time when the electricity rate is low, such as midnight. The opening / closing unit 140 includes a power detection sensor 142 for detecting power consumption and time of the user load 150. The power detection sensor 142 can separately detect the power supplied from the power storage facility 110 and the power supplied via the power company distribution network 202. The user load 150 includes a refrigerator, a microwave oven, a cooking device, a washing machine, an air conditioner, a TV, an audio device, a personal computer, a game machine, and the like at home, and a personal computer, a copying machine, OA equipment such as facsimiles and printers, and air-conditioning equipment. In stores, various facilities such as lighting fixtures, exhibits and vending machines, or nearby facilities and incidental facilities such as traffic lights and street lights. It is.

There are two watt-hour meters 160, a watt-hour meter 162 on the power purchase side and a watt-hour meter 164 on the power sale side, and the watt-hour meter 162 is the power purchased via the distribution network 202 of the power company (the purchased power) The watt hour meter 164 measures the electric power sold through the distribution network 202 of the electric power company (referred to as the electric power sold). The watt hour meters 162 and 164 may measure the amount of power and the time. Furthermore, if a function to communicate with home appliances, various electronic devices, and electrical devices provided as the user load 150 and to manage the power consumption for each electrical device is added, the power consumption for each electrical device and each hour Can be measured, and the value can be set with respect to the power consumption mode of the electric device and the usage time of the electric device .

  The power company includes a network terminal 204 in addition to the distribution network 202 that supplies so-called commercial power to the user, and performs data communication with the power storage system 100 and the management server 400 of the present invention. The terminal 204 can receive power information stored in the management server 400 and give a control instruction to the power storage system 100. For example, an instruction is given to forcibly discharge the user's power storage facility 110 at a time required for the electric power company to reduce the peak of the amount of power generation. Alternatively, in order to level the operation of the power generation facility and improve efficiency, instructions such as starting and stopping are transmitted to store electricity at midnight. Such a compulsory function may be included in the contents of the contract with the owner of the power storage system and may be rejected, and may provide advantageous conditions.

The management server 400 is installed, for example, in a company that aggregates the power value generated by the power storage equipment installed in the user and mediates between the value provider and the value acquisition desireer. 100 is a device that manages information about 100 and contractors and provides such information. As shown in FIG. 1, the management server 400 mainly includes a contractor information database 402, a value acquisition applicant database 404, a data processing / storage unit 406, an information disclosure unit 408, and each of these parts. An information management unit 401 that acquires, processes, and provides information is configured.
The contractor information database 402 stores information (name, address, device identification number, power information, personal hobbies, etc.) regarding the contractor who has installed the power storage system 100. The contractor information is stored in advance in the database 402 by using an input device (not shown) or by downloading from the power storage system 100 by communication before the contractor uses the management system.

The value acquisition applicant database 404 is information (name, address, desired item, desired electric energy, acquired electric power unit, acquired information) regarding a person who wants to acquire the value of electric power generated by the power storage system 100 (value acquisition applicant). (E.g., consideration or goods that can be provided for electricity). Like the contractor information, value acquisition applicant information stored in the database 404 is also stored in advance before the start of system use.
The data processing / storage unit 406 stores data relating to the value of power. The information disclosure unit 408 stores disclosure information that can be viewed by the contractor. The information management unit 401 transmits / receives various information to / from the power storage system 100, classifies, evaluates, determines, etc., the value of power using the obtained power information, generates compensation information, stores, generates disclosure information, Processing such as storage is performed.
In addition, the information management unit 401 including the contractor information database 402, the value acquisition applicant database 404, the data processing / storage unit 406, and the information disclosure unit 408 as described above is not provided in the management server 400, but each You may provide in the electrical storage system 100. FIG. In this case, the charge of electricity can be determined in a self-contained manner within the power storage system . Then, when each power storage system 100 discloses the consideration, the management server 400 connected via the network can refer to the decided consideration.

The value acquisition applicant 500 includes a network terminal 501 connected to the management server 400 via the network 300 and a power consumption meter 502. Here, the network terminal 501 gives its own desired information to the management server 400 or obtains disclosure information from the management server 400. The power consumption meter 502 measures the amount of power actually used by the value acquisition applicant. For example, the power consumption meter 502 is used to offset the power of the value provider and the value acquisition applicant on the system. It is what is done.
The network terminal 600 is a terminal that allows a contractor to access the management server 400 via the network 300. With this network terminal 600, the contractor can confirm his / her power information, and can refer to consideration information, advertisement information, etc. provided by the value acquisition applicant.

  FIG. 2 shows an embodiment of a power storage system 102 combined with a solar power generation facility in which the power storage system has a solar cell array 112 as a solar power generation facility and the power storage facility 110 is charged with electric power from the solar cell array 112. The control unit 125a detects the output of the solar cell array 112 and controls whether to charge the power storage facility 110 with the output of the solar cell array 112 or to receive and charge commercial power from the distribution network 202 of the power company. It is. When the output from the solar cell array 112 is obtained, the amount of charge of the power storage facility 110 and the operation status of the user load 150 are viewed. If the power storage facility 110 is not fully charged, the power storage facility 110 is charged, and surplus power If there is, control is performed so that power is sold to the power company's distribution network 202 by reverse power flow. When the power storage facility 110 is not fully charged and no output is obtained from the solar cell array, commercial power is received from the power company and charged. Other parts are the same as those in FIG.

<Information processing in power storage systems>
First, the process of acquiring and generating power information of the power storage system 100 will be described. Since the power storage systems of FIG. 1 and FIG. 2 are substantially the same operation, they will be described below simultaneously.
FIG. 3 shows a flowchart of the power storage system 100 of the present invention.
When power is received by the power storage facility 110 (charging of the power storage facility) or power consumption from the power storage facility to the user load (discharge of the power storage facility) is generated, current is supplied to the DC / AC inverter unit 122 that can perform bidirectional conversion. Since the current flows, the control unit 125 controls this current and can confirm the start and stop of the power storage system and the charging and discharging according to the operation state of the DC / AC inverter unit 122. In step S <b> 11 of FIG. 3, the start-up state or the stop state of the power storage system is confirmed according to the operation state of the DC / AC inverter unit 122. The start-up state or the stop state of the power storage system is confirmed, and if it is operating, information about power is acquired from the power detection sensor 142 (step S12). From the power detection sensor 142, charging information of the power storage equipment, discharging information, or consumption information by the user load 150 can be obtained.

Next, in step S <b> 13, the power conditioner 120 acquires the charge information, discharge information, or consumption information and stores it in the data storage unit 126. Here, for example, assuming that the power information is aggregated and transmitted to the management server 400 every day, the power storage system 100 adds and subtracts the stored power amount and the power amount supplied to the load, respectively, for one day. The amount of electricity is counted. However, the transmission unit is not limited to every day, and may be one week or one month. The addition / subtraction of the electric energy is not limited to simple addition / subtraction, but may be performed for each time, for each type of load, or for each type of charging power. Addition / subtraction is facilitated if these sections are weighted and aggregated.
In step S14, the control unit 125 creates transmission information using the totaled charging information, discharging information, and consumption information. The transmission information includes identification information of the contractor who owns the power storage system 100, the amount of stored power, the amount of discharged power, the time of storage, the time of discharge, the consumption mode, and the like. In step S <b> 15, the communication interface 124 transmits the created transmission information to the management server 400 via the network 300. This transmission information corresponds to the power information described above.

<Information processing in the management server>
Next, information processing in the management server 400 will be described.
FIG. 4 shows a flowchart of information processing by the management server 400 of the present invention.
This information processing is executed by the information management unit 401.
First, in step S41, it is confirmed whether or not there is received data. If data is received from the communication interface 124 of the power storage system 100 or the network terminal 501 of the value acquisition desirer 500, the process proceeds to step S42. In step S42, the information management unit 401 confirms the content of the received data and determines whether or not the power information is from the power storage system. In the case of power information, the process proceeds to step S43. In step S43, the information management unit 401 analyzes the received power information and stores it in a predetermined storage unit or database. That is, the contractor identification information included in the power information is confirmed, and the received power information is stored in the storage area for the contractor in the contractor information database 402.

On the other hand, when the information management unit 401 analyzes that the received data is not power information but consideration information from the value acquisition applicant 500, the received data is acquired as value acquisition applicant information in step S47. And stored in the value acquisition applicant database 404. In addition, in the case of including information for identifying the value acquisition applicant himself, consideration information provided by the value acquisition applicant, advertisement information, etc., the value acquisition request in the value acquisition applicant information database 404 corresponding to the information The received information is stored in the storage area of the person's information. Alternatively, when the received data is contractor information from the storage system owner, information for identifying the contractor itself, contract information for acquiring the consideration of the contractor, and information on the contractor in the value acquisition applicant database 402 The received information is stored in the storage area. After obtaining and storing information in step S47, the process returns to step S41 and enters a data reception standby state.
After saving the power information in step S43, the process proceeds to step S44, and it is confirmed whether or not the contractor who provided the power information has already made a consideration contract. If there is a consideration contract, the process proceeds to step S45, and if not, the process returns to step S41. Here, the consideration contract refers to a value acquisition contract corresponding to the amount of electric power that the contractor A has concluded with the business operator B who is a power value acquisition applicant.
The consideration contract information is stored in advance in the contractor information database 402 by the processing in step S47. For example, in step S44, if there is information in the contractor information database 402 that the contractor A of the received power amount data has contracted with the business operator B, the process proceeds to step S45.

In step S45, the contents of the consideration contract are checked, and it is confirmed whether or not the current state of the contractor satisfies the value acquisition condition. Here, whether the price is calculated based on the price information stored in the two databases 402 and 404, the data processing / storage unit 406, and the received power information, and whether or not the content (condition) of the price contract is satisfied. Judging.
When the consideration contract condition is satisfied, it is determined that the value acquisition condition has been established, and the process proceeds to step S46, and based on the content of the consideration contract, the condition establishment information indicating that the condition has been established is the contractor who has concluded the consideration contract. Send to both A and operator B. If the value acquisition condition is not established, the process returns to step S41.

<Specific example of consideration contract in step S45>
A specific example of step S45 will be described.
Assume that the following information regarding the contractor A is stored in the contractor information database 402.
(A-1) Specific information of contractor A: name, address, ID number, telephone number (A-2) Consideration contract information: contractor name B, provider ID number (A-3) Depending on the current power storage equipment Accumulated electric energy that stores midnight power and uses it in the daytime: 1400 kWh

Further, it is assumed that the following information on the contractor name B is stored in the value acquisition applicant information database 404.
(B-1): Specific information of the operator name B: Name, address, ID number (B-2): Acquisition desired total electric energy = 30000 kWh
(B-3): Consideration information:
(1) Target product = Garden chair (2) Electricity required for replacement 1500 kWh First 20 people (3) Contractor stores late-night electricity and uses it in the daytime and company B uses it for manufacturing products It is necessary to offset the generated electricity and display it on the designated label to allow it to be used for promotional activities.

Here, the designated label means, for example, a label as shown in FIG. 5, and the business operator B affixes this label to its own product and sells it in order to promote sales of its own product. On the other hand, as a price, the business operator B promises the contractor to provide the business product of the business operator B (for example, a garden chair).
Here, as a specific example, the content of the consideration contract between the contractor A and the business operator B is “when one of the garden chairs is stored when the total amount of accumulated electric energy stored in the daytime and used in the day reaches 1500 kWh. For free ".
In such a situation, in Step S45, the current late-night power of the contractor A is stored, and the accumulated power amount used in the daytime is compared with the value acquisition condition (1500 kWh) of the value contract contents of the business operator B. The

In the condition setting (A-3) described above, the accumulated power amount (1400 kWh) used for storing the current midnight power of the contractor and used in the daytime has not yet reached the total power amount, so the process returns to step S41 as it is. .
On the other hand, if it is assumed that the accumulated power consumed during the daytime when the contractor A stores the late-night power reaches 1500 kWh, this has reached a preset value acquisition condition (1500 kWh). It is determined that the condition is satisfied.
In this case, the process proceeds to step S46, and both the contractor A and the operator B are notified that the condition is satisfied. Thereafter, the business operator B who has confirmed the notification of the establishment of the condition delivers one promised garden chair to the contractor A.
In the label of FIG. 5, the amount of electric power whose value was acquired based on the results of the previous year is expressed (the portion corresponding to 5%), but was measured by the power consumption meter 502 shown in FIG. By expressing the power amount determined based on the power amount as a reference, a display with a small time difference is possible, which is preferable.

By performing the series of processes as described above, various benefits can be given to those who are related to the power storage management system. For example, even if a user (equivalent to the contractor A) who has installed the power storage system 100 contributes to improving the environment by storing midnight power and using it in the daytime, until now the daytime and nighttime of the power rate menu Although the economics were only discussed based on the price difference, a consideration (gardening chair) can be obtained by this system.
In addition, for a person who provides a power storage system, economic benefits can be obtained if more users are to introduce power storage facilities by obtaining compensation. Furthermore, not only for providing power storage systems, but also for general business operators (equivalent to contract business operator B) to users who can expect to purchase their products instead of giving consideration to the contractors. It can be promoted as an effort to improve the environment by conducting strong advertising (equivalent to labeling).

In the above description, the value is determined in the management server. However, the present invention is not limited to this. For referring to the data of the management server, the system on the power generation facility side and the power information can be viewed. It is also possible to determine the price on a personal terminal.
In other words, the time shift of electricity by the electricity storage system creates new value, and the owner of the electricity storage system can get compensation by acknowledging that value, and the business that purchased (acquired) that value. Can benefit from being able to advertise efficiently and easily to prospective purchasers of their products instead of giving consideration to the owner of the storage facility.
In the above specific example, the self-generated power and the business operator B in the production of the product out of the self-generated power are provided on the condition that the self-generated power amount for the self-consumption and the business operator use for appealing to the environment. Although an example has been shown in which a value is obtained by offsetting the power used, various values can be considered as targets of value.

Examples of the value obtained by storing late-night power and using it during the daytime include the following.
(1) Value to the extent that it contributed to emission reduction, such as carbon dioxide, due to the difference in CO2 emission intensity between daytime and late-night electricity.
(2) Value for contributing to the reduction of commercial power generation costs (operating expenses, installation expenses, etc.) by selling power to power companies and contributing to load leveling.

Such values are digitized and stored in the data processing / storage unit 406 in advance.
The above value can be calculated if there is data on the amount of electricity used in the daytime when storing late-night power and the time, and for example, 1 kWh is set as 1 point, the point system is set, and the point is monetary It is also possible to add value. Furthermore, regarding time zone information, it is possible to add not only the time but also seasonal factors. For example, for power obtained by shifting the power of midnight to summer daytime (within a certain period of time within a certain period), 1 kWh is set to 2 It is also possible to set points in detail, such as points. In the case of the point system as described above, the conversion of the electric energy and the point may be performed uniformly, or the value acquisition applicant may arbitrarily set based on the profit of the value acquisition applicant. It doesn't matter.

The business operator B (value acquisition applicant) may appropriately set, for example, a product, money, a voucher, etc. to be given to the contractor as a consideration based on the number of points.
When using such value evaluation standard (1), in step S45, instead of using the power consumption amount for checking the condition, the power information is referred to for the target power amount, and the data It is only necessary to perform a process of converting (processing) into a point, calculating a point, and comparing the point with a preset value acquisition condition.
As described above, the numerical data stored in the data processing / storage unit 406 is used to convert the power consumption into the value data as described above.

The data processing / storage unit 406 may store information such as an element that determines the value and the importance of the element. In the above, an example of power generation and consumption time is shown, but as other “elements”, the type of power generation equipment, the consumption form, and the like can be used.
“Importance of elements” means weighting of evaluation, giving high importance to power generated during midsummer daytime, and giving low importance to generated power during times of low demand. means.
Using such factors and importance information, the value of power consumption is set in consideration of factors such as the quality of power consumption, time of consumption, and equipment size, as well as the amount of power consumption received. can do.

  Next, a specific example of an embodiment in which the contractor selects one of the considerations when there are a plurality of considerations will be described. Here, description will be made with reference to the example of the power storage system with the solar power generation device shown in FIG. The basic configuration, operation, and flowchart are the same as those in the first embodiment. In this system, generated power information generated using a solar power generation apparatus is further added. With regard to this power generation information, for example, it is conceivable to set a high value when power is generated by a solar cell during midsummer daytime and a user load or reverse power flow to the system is performed. When the power generation facility and the power storage system coexist in this way, each value can be converted into a preset point so that it can be easily quantified. As a specific example, a case where a power point is set and its value is distributed will be described.

<Power point standard>
When 1 kWh = 2 points are given • When the power generated by photovoltaic power generation is time-shifted and consumed between 12:00 and 16:00:
When 1 kWh = 1 point is given ・ When power generated by photovoltaic power generation is consumed outside the above hours ・ When midnight power is stored using a power storage system and power is consumed between 12:00 and 16:00

It is assumed that the following information is stored in advance in the information storage unit of the management server 400.
Information stored in the value acquisition applicant information database 404 (1) Provider: A company B that manufactures and sells garden goods.
Conditions: Posting of support status on the environmental contribution website.
Consideration: Provide garden chairs free of charge.
Necessary power points: 1000 points Acquisition desired power: 30000 kWh (first 30 people)
(2) Provider: Company C that sells pesticide-free vegetables by courier.
Conditions: Posting of support status on the environmental contribution website.
Consideration: Delivering a pesticide-free vegetable set free of charge.
Necessary power point: 1500 points Acquisition desired electric energy: 30000 kWh (first 20 people)
(3) Provider: Provider D providing air service.
Conditions: Posting of support status on the environmental contribution website.
Consideration: Domestic air ticket selected from specified date (round trip)
Necessary power point: 3000 points Acquisition desired electric energy: 30000 kWh (first 30 people)

Disclosure information stored in the disclosure information storage unit 408 (4) Consideration (garden chair) of operator B and necessary power point (5) Consideration of operator C (non-pesticide-free vegetable set) and necessary power point (6) Business Consideration of subscriber D (domestic air ticket selected from the designated date) and required power points (7) Contractor A's current exchangeable accumulated power points

  Here, it is assumed that the disclosure information stored in the disclosure information storage unit 408 is in a state where it can be browsed at least when a contractor or a value acquisition applicant accesses the management server 400.

FIG. 6 shows a flowchart for selecting a consideration in the present invention.
Under the circumstances as described above, the contractor A connects to the management server 400 from a terminal, for example, and performs a browsing confirmation request operation for the disclosure information. When the management server 400 receives the browsing confirmation request (step S61), the disclosure information of the contractor A is transmitted to the contractor A (step S62). This disclosure information is displayed on the terminal of the contractor A or the like. With this disclosure information, the contractor A can confirm his current exchangeable power point. At this time, it is assumed that the power amount points exchangeable with the consideration stored in the disclosure information unit 408 are 3100 points.

  In addition, the contractor A who has confirmed that the power amount points that can be exchanged for the current consideration is 3100 points, searches or confirms whether there is a compensation that can be acquired with this power consumption. Assuming that there are three considerations that can be acquired with the amount of power consumed by the contractor A in the disclosed information sent as shown in the above (4) to (6), the contractor A Confirm that there is consideration information provided by the person (B, C, D).

If the contractor A has a desired consideration in the three consideration information, the contractor A selects the consideration. For example, the contractor A performs an operation of selecting the desired domestic air ticket from the domestic air tickets on the designated date provided by the business operator D. By this operation, the selected information (value selection request) is sent to the management server 400. When the information management unit 401 of the management server 400 receives this request (step S63), the information management unit 401 determines that the exchange of power consumption and consideration has been established between the contractor A and the business operator D, and the contractor A and business Consideration determination information indicating that the consideration exchange contract has been established is transmitted to the person D (step S64).
Then, the business operator D confirming that the consideration exchange contract has been established with respect to the contractor A sends the domestic air ticket selected from the designated date to the contractor A.
As described above, when there are a plurality of considerations that can be exchanged for the power consumption of the contractor A, the consideration information is disclosed to the contractor A. Can be selected.

In the above embodiment, solar power generation is mentioned as the power generation equipment, but other types of power generation with a small environmental load are naturally applicable to systems using wind power generation, fuel cells, micro hydroelectric power generation, and power generation equipment using gas engines. Applicable.
Furthermore, it is possible to set points finely according to the combination of the type of power generation equipment and the power generation time. For example, in wind power generation, fuel cell, micro hydropower generation, and power generation using a gas engine, there is no limit on the time to generate power, but there is a difference between the power generated during the day and the power generated during the night, or thermoelectric power that uses hot water in combination. It may be possible to make a difference depending on whether there is a co-payment.
For power storage facilities, it is possible to rank the power storage facilities according to the power efficiency of power storage and discharge, the environmental load during disposal, etc., and to differentiate the points according to the rank.
In this way, the definition of conversion to points is clarified, and by using a common unit as points, the management system of the present invention can be easily operated even if various systems are mixed.

<Mutual service of services with different industries>
Credit card, airline companies, various sales outlets, etc. are promoting frequent use of mileage services that aim to lock in users, point-based product acquisition, and cash exchange systems. Specific examples of mutual services with such services are explained. To do.
In this case, it is necessary to convert the amount of power obtained from the power information into points or the like based on the value information and handle it as a common unit. The mutual service with the card company is explained below.

Point standard 1 kWh = 2 points ・ When power is generated by solar power generation and power is consumed between 12:00 and 16:00 (including time shift by storage battery)
・ When power is generated by a fuel cell with a cogeneration system and power is consumed between 12:00 and 16:00 (including time shift by storage battery)

1 kWh = 1 point-When power generated by solar power is consumed outside the above hours-When power generated by a fuel cell is consumed outside the above hours-Midnight power is stored using a power storage system, from 12:00 When power is consumed during 16:00

J company card usage amount: 2 points per 10,000 yen

Information on Contractor Z when Contractor Z, who owns a 3kWh solar power storage system with a storage system, pays using Company J's card, such as annual living expenses and communication expenses, and the total payment is 1 million yen Is as follows.
(Z-1) Specific information of contractor Z: Name, address, ID number, telephone number (Z-2) Consideration contract information: TBD (Z-3) Current exchangeable point equipment 1: Exchange by using 2000 point card Possible points: 200 points (use amount 100 million yen)

  Except for using the contractor information, it is possible to exchange the consideration by the same method as in the first and second embodiments. When the contractor Z uses points that can be exchanged, it can be exchanged for a value equivalent to 2200 points.

In addition, due to the entry of a new electric power company, there is a possibility that the price to be set among a plurality of companies may be different even at the same time and time.
In such a case, the information stored in the data processing / storage unit 406 or the like is updated each time so that the power value is not fixedly set in advance but can be flexibly dealt with fluctuations and differences in the power value. It is preferable to be able to do this.
In this way, if the value of electric power is changed according to various situations, the contractor's awareness of energy saving and energy creation can be increased, and the mutual benefit of the contractor and the operator can be improved more accurately. Furthermore, introduction of power storage equipment can be promoted.
In addition, from the viewpoint of the diffusion of power storage facilities and power generation facilities, it is necessary for many users to install the power generation facilities themselves. However, at present, a large amount of funds is still required for the introduction of equipment, so even if you do not introduce the equipment yourself, you will be asked to invest in the introduction of equipment by a third party and pay for the investment It is converted into points determined by the amount of electricity corresponding to the number of times of participation in the management system of giving, energy-saving related events, or the number of times and the amount of use of the building where the power storage facilities and power generation facilities are installed. If a management system of giving at the time of acquisition is formed, power storage equipment and power generation equipment can be spread, though indirectly.

<In case of office>
The demand for electric power in offices and the like continues to grow, and in order to reduce CO2 emissions in the future, it is effective to improve the power consumption of offices. An example in which the system of the present invention is used for office office equipment will be described using a case of a copying machine.
In this case, the storage battery equipment installed for each copier, or the total of the power storage equipment of multiple copiers that have power storage equipment, is regarded as one power storage equipment. It becomes equipment.
Copier: Sharp compound copier AR-L501 (average power consumption is 173 Wh)
Number of copiers with storage facilities: 50

The power storage equipment provided in the copier above is set so that midnight power equivalent to 3 hours is stored in terms of average power consumption, and power is supplied from the power storage equipment at 12:00 to 15:00.
With the above system, a power shift of 25.95 kW / day is possible, and a power shift of 6,228 kW / year is possible if the business day of the office is 240 days.
If this is handled in the same way as in the case of Example 2, 6,228 points can be obtained annually, and it can be handled as a similar mechanism. It is realistic to use such a power plan because a power rate menu such as “Naru” is set.
Many recent copiers are multifunction machines (with fax functions) and are office equipment already connected to the telephone line, so there is little additional equipment required besides the power storage device, and the present invention is implemented. It is a suitable office equipment to do. In this case, the copier with power storage equipment may be owned by the user, or as a business model for current copiers, a lease contract is charged according to the amount used, or a lease company contracts with the power company. It can be considered to enjoy profits.

<For traffic signals>
LED-type traffic lights that can reduce the power consumption of traffic lights are becoming popular. Since the LED traffic light is considerably smaller than the power consumption of conventional traffic lights, it can be operated with a relatively small power storage facility that does not hinder the installation.
Here, a case where the present system is applied to a traffic light will be described.
Traffic light power consumption (per intersection): 300W
Number of storage equipment installed traffic lights: 1,000 formulas The storage equipment installed in the above traffic signal system stores midnight power equivalent to 3 hours in terms of average power consumption, and supplies power from the storage equipment at 12:00 to 15:00. Set as follows.
With the above system as a whole, a power shift of 900 kW / day is possible, and since the traffic light operates 365 days, a power shift of 328,500 kWh / year is possible.
The traffic signal is a public facility, which differs from the previous examples, but by contracting with the power company, the use of late-night power can be promoted to save the electricity bill required for the traffic light, or CO2 emissions can be reduced (late night Quantifying the difference in CO2 emissions between electric power and daytime power and adding it to the national reduction target) makes it possible to obtain public benefits. Furthermore, by providing a power supply, it is possible to turn on a signal with electric power from the power storage facility in an emergency, which is a very useful facility for dealing with disasters.
