Transaction system and method for surplus power consumption of buildings {POWER TRADING SYSTEM AND METHOD FOR POWER CONSUMPTION URPLUS}

The present invention relates to a trading system and method for the surplus power consumption of a building.

Recently, due to the increase in new renewable energy facilities such as solar power generation, wind power generation, and fuel cells, power production by individuals rather than power companies is increasing. The power produced from such renewable energy facilities is often consumed in the power load of buildings, especially in accordance with government policies such as zero energy buildings, and the surplus of power remaining after being consumed in the building is stored in a power storage device. It can later be consumed by the building's power load or sold to power companies or other power loads.

Disadvantages arise.

Meanwhile, sales of electric vehicles are increasing due to increased interest in the environment and government encouragement policies. In addition, facilities for charging electric vehicles are increasing in proportion. Most electric vehicles are charged with power supplied from the power company's power grid.

Figure 2 is a flow chart showing a trading method for the surplus power consumption of a building according to an embodiment of the present invention.

Hereinafter, a trading system for surplus power consumption of a building according to an embodiment of the present invention will be described in more detail with reference to the attached drawings.

Figure 1 is a conceptual diagram schematically showing a trading system for surplus power consumption of a building according to an embodiment of the present invention.

Referring to FIG. 1, the trading system for surplus power consumption of a building according to this embodiment serves to trade power between power suppliers and power consumers. Here, 'power supplier' refers to the owner of at least one renewable energy facility 10 that produces electricity, and 'power consumer' refers to the owner of an external power load, for example, an electric vehicle (EV). do. Accordingly, the trading system for the surplus power consumption of the building substantially trades the power produced by the renewable energy facility 10 to charge the battery B of the electric vehicle (EV).

In particular, in this embodiment, the renewable energy facility 10 is for production of power consumed by the power load 20, and the power production pattern of the renewable energy facility 10 and the power load 20 In consideration of the power consumption pattern of ), the surplus, excluding the power consumed by the power load 20, from the power produced by the renewable energy facility 10 is charged to the electric vehicle (EV). Here, the 'power load 20' may mean, for example, various facilities that use power for the purpose of using the building or an electric device that is installed inside the building and uses power. The trading system for the surplus power consumption of the building according to this embodiment includes a plurality of charging stations 100, a plurality of supplier terminals 200, a plurality of consumer terminals 300, and a transaction brokerage server 400. .

More specifically, the charging station 100 supplies power to the external power load and may be referred to as a power supply station. The charging station 100 includes at least one charger 110 that charges the electric vehicle (EV) with a preset amount of supplied power among the power produced by the renewable energy facility 10. The charging station 100 may be located adjacent to or spaced apart from the renewable energy facility 10.

And the supplier terminal 200 generates power supply information and transmits it to the transaction mediation server 400. 'Power supply information' may be defined as including location information and the amount of power supplied of the charging station 100. For example, as the provider terminal 200, a computer provided in each of the charging stations 100 may be used, and may communicate with the transaction brokerage server 400 by wire or/and wirelessly to communicate with the transaction brokerage server 400. ) can transmit the power supply information. In addition, as will be described later, the supplier terminal 200 receives a transaction request signal from the consumer terminal 300 through the transaction brokerage server 400, and sends a transaction request signal to the consumer terminal through the transaction brokerage server 400. A transaction approval signal is transmitted to (300).

In particular, in this embodiment, the provider terminal 200 considers the power production pattern of the renewable energy facility 10 and the power consumption pattern of the power load 20, and The surplus, excluding the power consumed by the power load 20, from the power produced is set as the amount of power supplied to the charging station 100. Therefore, as described above, the surplus, excluding the power consumed by the power load 20, from the power produced by the renewable energy facility 10 is not stored in a separate power storage device, and the electric vehicle (EV) ) can be charged directly.

The supplier terminal 200 may receive a charging completion time from the charger 110 at which charging of the currently charging electric vehicle (EV) is completed. And the supplier terminal 200, when the electric vehicle (EV) is being charged in all the chargers 110 of the charging station 100, displays the charging completion time at the charger 110 as the transaction intermediary server ( 400).

Next, the consumer terminal 300 generates a matching request signal for matching the charging station 100 and the electric vehicle (EV) according to the power consumer's selection and transmits it to the transaction brokerage server 400. . Here, the 'matching request signal' can be said to be a signal that requests matching between the charging station 100 and the electric vehicle (EV) for charging the electric vehicle (EV) when selected by the power consumer. there is.

In addition, when transmitting the matching request signal to the transaction brokerage server 400, the consumer terminal 300 generates power demand information and transmits it to the transaction brokerage server 400 along with the matching request signal. . Here, 'power demand information' may be defined as including at least the current location information of the electric vehicle (EV), the charging rate and required charging amount of the battery (B). Additionally, the consumer terminal 300 accepts charging of the electric vehicle (EV) at any one of the charging stations 100 matched through the transaction brokerage server 400, as will be described later. The transaction request signal is transmitted to the consumer terminal 300, and the transaction approval signal is transmitted from the consumer terminal 300 through the transaction mediation server 400.

For example, the consumer terminal 300 may be understood as a smartphone or tablet PC owned by the electric power consumer. Accordingly, the consumer terminal 300 may substantially communicate wirelessly with the transaction brokerage server 400 and transmit the matching request signal and power demand information to the transaction brokerage server 400.

Meanwhile, the transaction brokerage server 400 matches any one of the plurality of electric vehicles (EV) with any one or more of the plurality of charging stations 100 to provide power between the power supplier and the power consumer. Broker the transaction. To this end, when the transaction brokerage server 400 receives a matching request signal from the consumer terminal 300, it compares the power supply information and power demand information transmitted from the consumer terminal 300 and the supplier terminal 200. Any one of the plurality of electric vehicles (EV) is matched with any one or more of the plurality of charging stations 100. And the transaction brokerage server 400 transmits the location information and power supply amount of the matched charging station 100 to the consumer terminal 300 of the owner of the matched electric vehicle (EV).

In particular, in this embodiment, if the transaction brokerage server 400 determines that a plurality of the charging stations 100 exist within the actual driving distance (Mr) from the current location of the electric vehicle (EV), the The charging station 100 located within the actual driving distance (Mr) from the current location of the electric vehicle (EV) is calculated by considering the charging rate of the battery (B) and the distance from the current location of the electric vehicle (EV). Matching is performed in a preset order according to at least one of the amounts of power supplied from the charging station 100. At this time, the transaction brokerage server 400 may calculate the actual driving distance (Mr) of the electric vehicle (EV) from the charging rate of the battery (B). For example, the transaction brokerage server 400 determines the charging rate of the battery B by considering the battery specifications according to the type of the electric vehicle (EV), that is, the driving distance when the battery is fully charged. Considering the charging rate in (B), the actual driving distance (Mr) of the electric vehicle (EV) can be calculated.

More specifically, when the charging rate of the battery (B) is less than the preset minimum charging rate or exceeds the minimum charging rate and exceeds the preset standard charging rate, the electric vehicle (EV) The charging station 100 located within the actual driving distance (Mr) from the current location of the electric vehicle (EV) is matched in order of short distance from the current location of the electric vehicle (EV). And, when the charging rate of the battery B is higher than the lowest charging rate and lower than the reference charging rate, the transaction brokerage server 400 determines the charging rate of the battery B at the current location of the electric vehicle (EV) and the lowest charging rate. The charging station 100 located within the lowest driving distance (Mm) calculated from the difference in charging rate is matched in order of the amount of power supplied by the charging station 100.

Such matching of the transaction mediation server 400 is to prevent the lifespan from being reduced as much as possible by considering the characteristics of the battery B. That is, in general, the lifespan of a battery is reduced when the charge rate is less than 20%, so it is desirable to charge the battery so that the charge rate of the battery is maintained at 20% or more.

For example, the standard charging rate may be set to 20%, and the standard charging rate may be set to 40%. And when the charge rate of the battery (B) is 10%, it is desirable for the battery (B) to be charged as quickly as possible. In addition, when the charging rate of the battery (B) is 50%, the chargeable power amount of the battery (B) is not large, so the driving of the electric vehicle (EV) is possible regardless of the amount of power supplied by the charging station 100. It is desirable for the distance to be minimized. Therefore, when the charging rate of the battery (B) is less than the minimum charging rate or higher than the reference charging rate, the transaction brokerage server 400 determines the actual driving distance (Mr ) are matched to the charging station 100 located within the electric vehicle (EV) in order of short distance from the current location. On the other hand, when the charge rate of the battery (B) is 30%, the chargeable power amount of the battery (B) is of a certain size, so the charge rate of the battery (B) is maintained in the range above the minimum charge rate. It is preferable that the battery B is charged so that its charging rate is maximized. Therefore, when the charging rate of the battery (B) is higher than the minimum charging rate and lower than the reference charging rate, the transaction brokerage server 400 is located within the actual driving distance (Mr) from the current location of the electric vehicle (EV). The charging stations 100 are matched in order of the amount of power supplied to the charging stations 100.

Matching as described above occurs when the required charging amount is not included in the power demand information transmitted from the consumer terminal 300. In this embodiment, when the transaction mediation server 400 includes the required charging amount in the power demand information transmitted from the consumer terminal 300, matching is performed differently from the method described above.

More specifically, when the required charging amount is included in the power demand information transmitted from the consumer terminal 300, the transaction brokerage server 400, if the charging rate of the battery B is less than the minimum charging rate, The charging station 100 located within the actual driving distance (Mr) from the current location of the electric vehicle (EV) is operated at the current location of the electric vehicle (EV) regardless of the amount of power supplied by the charging station 100. Match in order of distance. And, if the charging rate of the battery (B) is higher than the minimum charging rate and less than or equal to the reference charging rate or exceeds the reference charging rate, the transaction brokering server 400 determines the minimum driving distance at the current location of the electric vehicle (EV). Among the charging stations 100 located within (Mm) or within the actual driving distance (Mr), the charging station 100 whose power supply is more than the required charging amount of the electric vehicle (EV) Matches in order of distance from the current location of the electric vehicle (EV).

In addition, when the transaction brokerage server 400 matches a plurality of electric vehicles (EV) of the same charging station 100, the electric vehicle (EV) with a relatively low charging rate of the battery (B) Matches the charging station 100 only. That is, when there are two or more charging stations 100 with similar conditions compared to the power supply information and power demand information, the transaction brokerage server 400 determines that the charging rate of the battery B is relatively low. The electric vehicle (EV) is given priority for charging at the charging station 100.

And the transaction mediation server 400 corrects the actual drivable distance (Mr) (or minimum drivable distance (Mm)) by considering the variation of the charge amount of the battery (B) according to temperature. That is, if the daily average temperature exceeds or is less than the preset reference temperature band, the transaction brokerage server 400 determines the actual drivable distance (Mr) (or minimum drivable distance (or The charging station 100 located within the first corrected driving range (Ma1) (or the second corrected driving range (Ma2)) obtained by subtracting Mm)) by a preset ratio is located at the current location of the electric vehicle (EV). Matching is performed in a preset order considering at least one of the distance and the amount of power supplied from the charging station 100.

Meanwhile, when the transaction brokerage server 400 receives the charging completion time from the supplier terminal 200, the transaction mediation server 400 only applies the charging completion time to the electric vehicles (EVs) that can arrive within a preset arrival time before and after the charging completion time. The charger 110 matches the charging station 100 where the electric vehicle (EV) is being charged. To this end, the transaction brokerage server 400 calculates the travel time from the current location information of the electric vehicle (EV) to the charging station 100.

Hereinafter, a trading method for the surplus power consumption of a building according to an embodiment of the present invention will be described in more detail with reference to the attached drawings.

Figure 2 is a flow chart showing a trading method for the surplus power consumption of a building according to an embodiment of the present invention.

More specifically, in the supply information transmission step (S100), at least one of the supplier terminals 200 generates power supply information including the location information and the amount of power supplied to the charging station 100 and transmits it to the transaction brokerage server 400. ) is sent to. In the supply information transmission step (S100), if the electric vehicle (EV) is being charged in all chargers 110 of the charging station 100, the supplier terminal 200 receives the current charge from the charger 110. The charging completion time at which charging of the electric vehicle (EV) is completed is received and transmitted to the transaction brokerage server 400.

In particular, in this embodiment, in the supply information transmission step (S100), the supplier terminal 200 takes into account the power production pattern of the renewable energy facility 10 and the power consumption pattern of the power load 20, The surplus, excluding the power consumed by the power load 20, from the power produced by the renewable energy facility 10 is set as the amount of power supplied to the charging station 100.

Next, in the demand information transmission step (S200), at least one of the consumer terminals 300 sends a matching request signal for matching the charging station 100 and the electric vehicle (EV) and the electric vehicle (EV). Power demand information including the current location information and the charging rate of the battery B is generated and transmitted to the transaction brokerage server 400. In addition, in the demand information transmission step (S200), the consumer terminal 300 sends the power demand information further including the required charging amount of the electric vehicle (EV) to the transaction brokerage server 400 according to the power consumer's selection. ) can also be sent to.

And in the matching step (S300), the transaction brokerage server 400 selects any one of the plurality of electric vehicles (EVs) at the charging station ( 100) matches with one or more of the following. And in the matching step (S300), the transaction brokerage server 400 provides location information and power supply amount of the charging station 100 matched to the consumer terminal 300 of the owner of the matched electric vehicle (EV). send. As described above, in the matching step (S300), the transaction brokerage server 400 selects the charging station 100 located within the actual driving distance (Mr) from the current location of the electric vehicle (EV). Considering the charging rate of the battery B, it is matched in a preset order according to at least one of the distance from the current location of the electric vehicle (EV) and the amount of power supplied from the charging station 100.
