Description

This relates to a system that predicts the amount of electricity required by a consumer in the future, and predicts the amount of possible power saving together with the date and time of power saving using the value of the predicted amount of required power. It also relates to a system that creates a power supply plan using information on the amount of possible future power saving and the date and time of power saving obtained by such prediction.

Demand control systems that reduce basic charges are becoming popular as a way to cut electricity bills. Demand control systems monitor the ever-changing power usage of consumers, and reduce the electrical output of power-using devices or turn off the power to ensure that power usage does not exceed a demand value determined at 0 minutes and 30 minutes past the hour.

Patent Document 1 discloses a demand control system that includes an electric power pulse generator that generates an electric power pulse signal according to the amount of electric power supplied to an electric power load, and a demand power monitor that monitors the demand power consumed by the electric power load. The demand power monitor includes a target demand power setting means that sets a target demand power, a power consumption calculation means that calculates the demand power, and a power comparison means that compares a partial demand power of a partial measurement time into which the demand power measurement time is divided with a partial target demand power corresponding to that partial measurement time, and the target demand power setting means sets the target demand power based on an outdoor discomfort index. However, Patent Document 1 does not disclose the idea of predicting the amount of electric power that can be saved, or creating a power supply plan from information on the predicted amount of electric power that can be saved.

Patent Publication 2018-196299

The system according to the present application has an objective of predicting the future amount of power that can be saved by predicting the future amount of power used by consumers. Another objective is to provide a system that discloses information on the predicted amount of power that can be saved. Another objective is to obtain a system that creates a power supply plan based on the predicted future amount of power that can be saved and information on the date and time of power saving.

Because electricity savings result in reduced electricity usage fees, monetary value is attached to energy savings. Therefore, the objective of this system is to provide a system that allows the electricity resulting from energy savings to be credited and thus made available for buying and selling.

(1) The problem is solved by a power saving prediction system that predicts and obtains the amount of power Ws that consumer a can save at a future date and time Tf, the power saving prediction system including: a means for acquiring an amount of power Wc that is obtained based on comfort index information for a date and time Tf that is the same date and time as the future date and time, the amount of power Wc that consumer a can save comfortably at the date and time Tf; a means for acquiring an amount of power Wr that is predicted to be actually required by consumer a at the date and time Tf; and a means for calculating Wc-Wr, and when Wc-Wr is a positive value, the positive value is set as the power Ws that consumer a can save at the date and time Tf.
(2) The problem is solved by the power saving prediction system described in (1), characterized in that the means for acquiring the amount of power Wr acquires weather information for a future date and time Tf predicted at the location of consumer a, and uses information on the amount of power required for consumer a to be comfortable in the event of weather similar to the weather related to the weather information, and acquires information on equipment with relatively high power consumption predicted to be used at the location of consumer a at date and time Tf that is the same as the future date and time Tf, and predicts the amount of power Wr using information on the amount of power required when similar equipment is operating.
(3) The problem is solved by a power supply planning system that plans power supply using information on the power Ws that consumer a can save at a future date and time Tf, obtained by the system in (1), and when information is obtained that there is power Ws that consumer a can save at a future date and time Tf at a date and time Tf that is the same as the future date and time Tf, the power supply planning system plans to cancel the transmission of power Ws to consumer a at the date and time Tf that is the same as the future date and time Tf.
(4) The problem is solved by a power supply planning system that plans power supply using information on the power Ws that consumer a can save at a future date and time Tf, obtained by the system in (1), and when information is obtained that there is power Ws that can be saved in a specified area A including the location of consumer a at a future date and time, the power supply planning system plans to cancel the transmission of that power Ws to area A at the same date and time as the future date and time.
(5) A power supply planning system that plans power supply using information on the power Ws that consumer a can save at a future date and time Tf, obtained by the system of (1), in which when information is obtained that there is power Ws that consumer a can save at a date and time Tf that is the same date and time as the future date and time, and consumer b obtains information that consumer a wishes to take over the Ws in order to obtain the amount of power predicted to be actually required by consumer b at the date and time Tf, the problem is solved by the power supply planning system that plans to transmit the power Ws that was scheduled to be transmitted to consumer a at the date and time Tf to consumer b at the date and time Tf.
(6) A power supply planning system that plans power supply using information on the power Ws that consumer a can save at a future date and time Tf, obtained by the system in (1), wherein when information is obtained that there is power WS that can be saved in a specified area A including the location of consumer a at a future date and time, and information is obtained that a specified area B including the location of consumer b wishes to acquire the WS in order to obtain the amount of power actually predicted to be required in area B at the same date and time as the future date and time, the problem is solved by the power supply planning system that plans to transmit the power WS that was scheduled to be transmitted to area A at the future date and time to area B.

The power supply planning system can be executed not only by the CPU of the power supplier's computer, but also by the CPU of the administrator's computer.

The system according to the present application can predict the amount of power that can be saved in the future by predicting the future power usage of consumers. It can also disclose information on the predicted amount of power that can be saved. It can also provide a system that creates a power supply plan based on the predicted future amount of power that can be saved and information on the date and time of power saving. It can also make the power resulting from power saving into debt so that it can be bought and sold.

In "j. Disclosure information," information to be disclosed in "c. Power saving amount disclosure/transmission program" is recorded, and an example is shown in Figure 10.

[a. Power forecast processing program required for consumer a at date and time Tf]
The processing procedure of the program for predicting the power required by consumer a at date and time Tf is as follows (FIG. 3). The main body of the processing is the CPU of the administrator's computer. Here, Tp indicates a predetermined date and time in the past (the same applies in this specification). Tf indicates a predetermined date and time in the future (the same applies in this specification).

Location information of consumer a is obtained from "f. Consumer information" in the storage device 20, and weather information for a future date and time Tf for the location of consumer a is obtained via the Internet (S1). Weather information is information about weather conditions that affect power usage, such as weather, temperature, and humidity. Typhoon information is also subject to weather information. A past date and time Tp with similar weather information to the future date and time Tf for the location of consumer a is obtained via the Internet (S1). Power usage information of consumer a for the past date and time Tp is obtained from "f. Consumer information" in the storage device 20 (S1).

From "f. Consumer information" in the storage device 20, information on the number of employees at the future date and time Tf for consumer a is obtained (S2). From "f. Consumer information" in the storage device 20, information on a past date and time Tp for consumer a, which has the same number of employees as the number of employees at the future date and time Tf, is obtained (S2). From "f. Consumer information" in the storage device 20, information on the power usage of consumer a at the past date and time Tp is obtained (S2).

Operating equipment information for consumer a at a future date and time Tf is obtained from "f. Consumer information" in the storage device 20 (S3). Operating equipment information refers to equipment that uses a relatively large amount of electricity, such as refrigerators and printers. Information on a past date and time Tp at which the amount of operating equipment is similar to the future date and time Tf is obtained from "f. Consumer information" in the storage device 20 (S3). Power usage information for consumer a at the past date and time Tp is obtained from "f. Consumer information" in the storage device 20 (S3).

The power required by consumer a at a future date and time Tf is predicted (S4). Specifically, a calculation process is performed to obtain the sum of the amounts of power used obtained in S1, S2, and S3. This sum is set as the power required by consumer a at the predicted future date and time Tf (S4). The "predicted required power" is recorded in "h. Predicted required power information" of the storage device 20. Figure 8 shows an example of the recorded "predicted required power information."

[b. Program for predicting power that consumer a can save on date and time Tf]
The processing procedure of the program for predicting the amount of power that the consumer a can save at the date and time Tf is as follows (FIG. 4). The main body of the processing is the CPU of the administrator's computer.

From the "i. Predicted required power information" in the storage device 20, information on "the amount of power required by consumer a at date and time Tf" is obtained (S5).

Comfort index information for date and time Tf at the location of consumer a is obtained from the outside via the Internet (S6). Next, based on the comfort index information for date and time Tf, the amount of power that consumer a can save at Tf is predicted (S7). Specifically, based on the predicted comfort index information, the "amount of power required for consumer a to be comfortable at date and time Tf" is calculated, and the difference between the "amount of power required for consumer a to be comfortable at date and time Tf" and the "amount of power required for consumer a at date and time Tf" is the amount of power that consumer a can save at date and time Tf. If the "amount of power required for consumer a to be comfortable at date and time Tf" is smaller than the "amount of power required for consumer a at date and time Tf", there is a surplus of power, so consumer a can save power at date and time Tf. If the "amount of power required for consumer a to be comfortable at date and time Tf" is larger than the "amount of power required for consumer a at date and time Tf", there is a shortage of power, so consumer a cannot save power at date and time Tf. The acquired "potential power saving information (i.e., information on the amount of power that can be saved)" is recorded in "j. Predicted potential power saving information" in the storage device 20.

In a similar manner, information on the amount of possible energy savings is obtained for each of consumers b, c, d, e, f, g, and h. Here, consumers a, b, c, and d are located in area A, and consumers e, f, g, and h are located in area B. The values of the information on the amount of possible energy savings for each of consumers a, b, c, and d are added together to obtain information on the amount of possible energy savings for area A. The values of the information on the amount of possible energy savings for each of consumers e, f, g, and h are added together to obtain information on the amount of possible energy savings for area B. Figure 8 shows an example of the recorded "predicted information on the amount of possible energy savings."

[c. Power saving amount disclosure/transmission processing program]
The processing procedure of the program for the power saving amount disclosure and transmission processing is as follows (FIG. 5). The main processing unit is the CPU of the administrator's computer.

From "j. Predicted possible power saving information" in the storage device 20, information on the predicted possible power saving amount for each unit time (every 30 minutes) for areas A, B, and C is obtained (S8). Information on the predicted possible power saving amount for each unit time (every 30 minutes) for areas A, B, and C (Figure 10) is disclosed (S9).

The administrator and the power supplier agree on which of the "predicted possible power saving information" should be sent to the power supplier. For example, they may agree that if the "predicted possible power saving amount" exceeds 800 kWh, the administrator will send the "predicted possible power saving amount information" to the power supplier. Such an agreement may be made when it is appropriate for the power supplier to review its power supply plan if the possible power saving amount exceeds 800 kWh. Such an agreement is recorded in the data storage section "g. Power supplier information" of the storage device 20 of the administrator's computer.

The CPU of the administrator computer obtains the details of the agreement from the data storage unit "g. Power supplier information", and if the agreement is met, transmits "predicted possible power saving information" to the power supplier with which the agreement was made (S10).

The administrator and the consumer agree on which of the "predicted possible power saving information" should be sent to the consumer. For example, an agreement may be made that the administrator will send "predicted possible power saving information" regarding the amount of power saved by consumers in a specific area to the consumer. Such an agreement is made when a power shortage is anticipated for the consumer in the specific area. Such an agreement is recorded in the data storage section "f. Consumer information" of the storage device 20 of the administrator's computer.

The CPU of the administrator computer acquires the details of the agreement from the data storage unit "f. Consumer information" and, if the agreement is met, transmits "predicted possible power saving information" to the consumer with whom the agreement has been made (S11). The CPU of the consumer's computer that has acquired the specified "predicted possible power saving information" from the administrator performs processing for [e. Power supply request determination processing] described below (Figure 7).

It is determined whether there is a supply request from the specified consumer (S12). The specified consumer is the consumer to which the "predicted possible power saving information" was sent in S11. If the CPU of the consumer's computer determines not to make a power supply request as a result of [e. Power supply request determination process], the supply request from the specified consumer is "No", and if it determines to make a power supply request, the supply request from the specified consumer is "Yes" (S12).

If there is no supply request, the process ends. If there is a supply request, the supply request information is sent to the power supplier (S13), and the process ends. The CPU of the power supplier computer that received the supply request information uses the supply request information from the specified consumer in [d. Power supply plan creation processing program] (Figure 6) (S15).

[d. Power supply plan creation processing program]
The processing procedure of the program for generating a power supply plan is as follows (FIG. 6). The main processing unit is the CPU of the power supplier's computer.

A predetermined "predicted possible energy saving information" is received from the administrator (S14). The predetermined "predicted possible energy saving information" is information that the administrator sent to the predetermined electricity supplier in S10 of the energy saving disclosure/transmission process (Figure 5). A predetermined consumer's supply request information is received from the administrator (S15). The predetermined consumer's supply request information is information that the administrator sent to the predetermined consumer in S13 of the energy saving disclosure/transmission process (Figure 5).

A power supply plan for the target unit time in the target area is created (S16). A specific example is as follows.
[Example 1] The supply of power corresponding to the amount of power saving is stopped for the area corresponding to the "predicted possible power saving amount information" received in S14 and for the corresponding unit time.
[Example 2] Electric power corresponding to the supply request is supplied for the area corresponding to the "supply request information" received in S15 and for the corresponding unit time.
[Example 3] If the area and unit time corresponding to the "predicted possible power saving information" received in S14 match the area and unit time corresponding to the "supply request information" received in S15, the supply of power corresponding to the amount of power saving canceled based on S14 is used for the power supplied based on S15.

[e. Power supply request judgment processing]
The processing procedure of the program for power supply request determination processing is as follows (FIG. 7). The main processing unit is the CPU of the customer's computer.

The system obtains predetermined "predicted possible power saving information" from the administrator (S17). The predetermined "predicted possible power saving information" is the information sent by the administrator in S11 of the power saving disclosure/send process (Figure 5).

The CPU of the consumer's computer acquires "h. Predicted required power information" recorded in the administrator's computer. In "h. Predicted required power information", the "h. Predicted required power information" of the consumer is recorded for each unit time. The CPU of the consumer's computer determines whether the unit time of "required power" in the "h. Predicted required power information" of the consumer matches the unit time corresponding to the "predicted possible power saving information" acquired in S17 (S18). If they match, it is determined that the consumer is suitable for receiving a power supply, and supply request information is sent to the administrator (S19), and the process ends. If they do not match, the process ends.
