(3-1) Electric power transaction method between one supplier and a plurality of consumers First, an electric power transaction between one supplier of distributed power and a plurality of consumers receiving the supply of distributed power will be described.

(3-1-1) Supplier call Using FIG. 3, in a power transaction between one supplier and a plurality of consumers, users (distributed) of one facility A (second facility) on the supplier side A case will be described in which a power supplier starts a power transaction by making a supply request (second request) A. That is, a case where power trading starts with a supplier call will be described.

  In FIG. 3, the supply request A is a request for one facility A on the supplier side to supply the distributed power generated at the facility A to a plurality of facilities BE on the consumer side. In FIG. 3, the supply request A is approved (consent BD: demand request (first request)) at a plurality of facilities B to D (a plurality of first facilities) on the customer side, and the supplier side Distributed power is supplied from the facility A to a plurality of facilities B to D on the consumer side. On the other hand, the supply request A is not accepted by the facility E, and distributed power is not supplied from the facility A to the facility E. That is, a power transaction is performed between one facility A (one second facility) on the supplier side and a plurality of facilities B to D (a plurality of first facilities) on the consumer side. A specific flow will be described below.

Step S1: The user of the facility A inputs a supply request (second request) A for supplying the distributed power generated by the power generator 23A to the plurality of facilities B to E from an input unit (not shown) of the facility A.
The user of the facility A inputs a supply destination ID for specifying the supply destination from, for example, the input screen shown in FIG. Other power supply conditions indicating the desired unit price, the type of power generated by the distributed power, the supply time zone of the day, the period and presence / absence of notification of the personal information of the supplier, and additional conditions such as the supply source ID (distributed power addition Condition) can be entered. The type of power is, for example, the type of power generation source such as power generated by solar power, power generated by wind power, or power generated by a fuel cell system. Furthermore, when distributed power is supplied to a plurality of facilities, the supply ratio of distributed power for each facility may be input as an additional condition.

Further, the input content may include user related information and facility related information.
User-related information is, for example, the name of at least one of a distributed power supplier (users of facilities A, F, G, H, etc.) and a consumer (users of facilities B, C, D, E, etc.) And information for identifying individuals such as occupations. Here, the information for specifying an individual may be information for specifying one individual or information for specifying a plurality of individuals. For example, the name is information for identifying one individual. For example, in the case of a profession, the information specifies a plurality of individuals who are employed in the profession. By including user-related information in the input content, for example, the supplier can specify to which consumer the distributed power is supplied, and the consumer can provide the distributed power from which supplier. You can specify whether to receive.

  Facility-related information refers to at least one of facilities A, F, G, H, etc. (second facility) and facilities B, C, D, E, etc. (first facility), for example, stadiums such as facility names and baseball This information identifies the type of facility such as a concert venue and the facility such as the owner. Here, the information for specifying a facility may be information for specifying one facility or information for specifying a plurality of facilities. For example, in the case of a facility name, it is information specifying one facility. For example, in the case of the type of facility, the information is information for specifying a plurality of facilities corresponding to the type of the facility. By including facility-related information in the input contents, for example, it is possible to specify which facilities the supplier will supply distributed power to, and what facilities the customer will receive distributed power from. Can be specified.

The supply request is configured based on these input contents. The input content is not limited to the above-described input content as long as there is at least information for specifying the supply destination. In addition, the input content may include an environmental coefficient indicating a load on the environment.
When the distributed power management unit 25A of the facility terminal 21A (second facility terminal) receives the supply request A based on the above-described input content, the distributed power management unit 25A transmits the supply request A to the mediation processing unit 31 of the mediation terminal 30.

  The intermediary processing unit 31 refers to the storage unit 15 (FIG. 2) of the management terminal 11, and whether the facility A and the plurality of facilities B to E about to start the distributed power transaction are registered in the storage unit 15. Judge whether or not. When the facility A and the plurality of facilities B to E are registered in the storage unit 15, the mediation processing unit 31 advances the processing to steps S2-1 to S2-4. On the other hand, the mediation processing unit 31 does not accept the supply request A from the facility A when any of the facility A and the plurality of facilities B to E is not registered in the storage unit 15. In this case, for example, the mediation processing unit 31 notifies the distributed power management unit 25A that the supply request A cannot be accepted.

  Steps S2-1 to S2-4: The mediation processing unit 31 transmits the supply request A of the facility A to the plurality of facilities B to E. The distributed power management units 25B to 25E of the facility terminals 21B to 21E (a plurality of first facility terminals) of the plurality of facilities B to E receive the supply request A and, for example, the plurality of facilities B to E via display units (not shown). A supply request A is presented to each user.

  When the users of the plurality of facilities B to E receive the supply request A and approve the supply request A, they input the approval to the distributed power management units 25B to 25E through an input unit (not shown). In the case of FIG. 3, each user of the plurality of facilities B to D accepts the supply request A from the facility A. Here, the consent of the supply request A by each user of the plurality of facilities B to D is referred to as consents B to D, respectively. These consents are demand requests for the distributed power of the facility A by the facilities B to D.

  The consent to the supply request includes not only acceptance of all requests included in the supply request but also acceptance of only a part of the supply request. As described above, the supply request includes, for example, a desired unit price, a power supply condition indicating the type of power generated by the distributed power, a supply time zone within a day, a period, and the presence / absence of notification of the supplier's personal information. These additional conditions are included. The consent to the supply request may be acceptable for each of these additional conditions.

  For example, the user of the facility B can accept the desired unit price and power supply condition in the supply request A, and can accept only a part of the supply time period. The user of the facility C can also accept only a part of the supply request A for the desired unit price, power supply condition, and period. In this way, the consent may include information indicating that all of the supply requests are accepted, or information regarding a portion of the supply requests that has been accepted.

In addition, each user of the plurality of facilities B to E receives the presentation of the supply request A and inputs the disapproval to the distributed power management units 25B to 25E through an input unit (not shown) when the supply request A is not accepted. To do.
In the case of FIG. 3, the user of the facility E has input the disapproval of the supply request A to the distributed power management unit 25E.

Steps S3-1 to S3-3: The distributed power management units 25B to 25D of the facility terminals 21B to 21D transmit consents BD to the supply request A to the mediation processing unit 31.
Step S3-4: Meanwhile, the distributed power management unit 25E transmits a disapproval for the supply request A to the mediation processing unit 31.

Step S4: The mediation processing unit 31 transmits notifications of consents BD to the distributed power management unit 25A.
Although not shown in FIG. 3, the mediation processing unit 31 may transmit a disapproval for the supply request A from the distributed power management unit 25E to the distributed power management unit 25A. The distributed power management unit 25A, based on the fact that the consent to the supply request A is not received from the facility E, or based on the fact that the disapproval to the supply request A is received from the facility E, Control is performed so that distributed power is not supplied to the power source.

  Step S5-1: The distributed power management unit 25A instructs the power generation apparatus 23A to supply the distributed power to the plurality of facilities B to D based on the consents BD transmitted from the plurality of facilities B to D. . The power generation device 23A supplies the distributed power generated by the power generation device 23A to the plurality of facilities BD based on the information included in the supply request A and the consents BD. Here, for example, the power generation device 23 </ b> A supplies the distributed power to the power company 10, and the facilities B to D receive supply of a desired amount of power based on the supply request A and the like from the power company 10.

  For example, when a supply ratio for each of a plurality of facilities B to D is included in the supply request A as an additional condition, the distributed power management unit 25A generates power generators for the plurality of facilities B to D based on the supply ratio. The distributed electric power generated by 23A is supplied. For example, the distributed power management unit 25A notifies the facilities B to D of the amount of power that each of the plurality of facilities B to D can receive. Each of the facilities B to D receives power supply from the power company 10 according to the supply ratio.

Further, the mediation processing unit 31 may determine the supply ratio. Then, the mediation processing unit 31 may instruct the distributed power management unit 25A to supply the distributed power to the plurality of facilities B to D based on the determined supply ratio. Further, the mediation processing unit 31 may notify the facilities B to D so as to receive power supply based on the determined supply ratio.
Although the determination method of a supply ratio is not specifically limited, For example, the mediation processing part 31 may determine based on the content of consent BD with respect to the supply request A by each user of each facility BD.

  For example, the mediation processing unit 31 may determine the supply ratio according to the degree of coincidence by determining the degree of coincidence between the supply request A and the consents BD. For example, when the supply time is 8 hours in the supply request A, the supply time is specified as 2 hours in the agreement B, the supply time is specified as 5 hours in the approval C, and the supply time is specified in the approval D. Assume that 1 hour is specified. In this case, the mediation processing unit 31 sets the distributed power amount generated by the power generation device 23A as 1 based on the ratio of the supply time in each consent B to D, and the facility B has 2/8 of the distributed power amount. It can be determined that the supply amount is 5/8 of the distributed power amount for the facility C and the supply amount is 1/8 of the distributed power amount for the facility D.

  The mediation processing unit 31 does not need to determine the supply ratio when the distributed power generated by the power generation device 23A can sufficiently satisfy the demand for the distributed power of the facilities BD. In other words, the mediation processing unit 31 may instruct the distributed power management unit 25A to supply the distributed power required by each of the facilities B to D in a state of being satisfied. In this case, each of the facilities B to D receives a necessary amount of power from the power company 10.

  Step S5-2: The power generation device 23A determines that surplus distributed power is generated when the distributed power generated by itself is larger than the distributed power supplied to the facilities BD. In this case, for example, the power generator 23 </ b> A reversely flows surplus distributed power to the power company 10.

  Here, the facility A and the plurality of facilities B to D are included in the power transaction system 1 that can receive the supply of system power from the power provider 10. Therefore, as described above, among the distributed power generated by the power generation apparatus 23A of the facility A, the surplus distributed power remaining after supplying the distributed power from the facility A to the plurality of facilities B to D can be reversely flowed to the system power side. It is. Thereby, it is possible to promote efficient use of the surplus distributed power by causing the surplus distributed power to flow backward while preferentially supplying the distributed power to a specific facility.

  Step S5-3: The distributed power generated by the power generation device 23A may be less than the distributed power supplied to the facilities BD. In this case, for example, the facilities B to D receive supply of insufficient power from the grid power of the power company 10.

  Here, since the facility A and the plurality of facilities B to D are included in the power transaction system 1 that can receive the supply of the grid power from the power provider 10, as described above, the shortage power is generated by the grid power. Can be supplemented. Thereby, the demand of the electric power in the facility B can be satisfied almost without excess or deficiency.

Step S6-1: The power generation device 23A notifies the distributed power management unit 25A of the amount of distributed power supplied to the facilities BD, and the like. In this case, the power generation device 23A may notify the distributed power management unit 25A of the surplus distributed power amount that has been caused to flow backward by the power provider 10.
Step S6-2: The distributed power management unit 25A notifies the mediation processing unit 31 of the supply amount of distributed power to the plurality of facilities B to D and the like.

  Note that the power generation device 23A may notify the mediation processing unit 31 of the supply amount to the plurality of facilities B to D, and the like. Further, the distributed power management units 25B to 25D may notify the mediation processing unit 31 of the amount of power supplied by the plurality of facilities B to D.

Step S7-1: The mediation processing unit 31 notifies the distributed power management unit 25A of the details of the distributed power supply amount based on the distributed power supply amount from the power generation apparatus 23A to the plurality of facilities B to D. Here, the unit price of the distributed power is, for example, a desired unit price input by the user of the facility A.
The distributed power management unit 25A presents the details to the user of the facility A via a display unit (not shown).

  Steps S7-2 to S7-4: The mediation processing unit 31 notifies the distributed power management units 25B to 25D of the details of the received amount based on the supply amount of the distributed power to each of the plurality of facilities B to D. .

  The distributed power management units 25B to 25D present each specification to each user of the facilities B to D via a display unit (not shown). For example, the details shown in FIG. 5 are presented to each user of the facilities B to D. In FIG. 5, for example, details for one month in October are shown, and the power source composition ratio, purchase unit price, purchase amount, and the like are shown for each supply source. The power source composition ratio indicates the ratio of the supplied power for each type of power including power generated by solar power generation, power generated by wind power generation, and power generated by a fuel cell system. In addition, the specification may include an environmental coefficient indicating a load on the environment and a distributed power supply time zone.

In addition, although the example of the detail of each user (electric power consumer) of facilities BD was shown in FIG. 5, it is the same for the user of facility A (electric power supplier) in step S7-1. Details may be presented.
In this way, the details are transmitted as distributed power supply information to each facility terminal between the facilities where the distributed power transaction has been performed. Users of the facility can check supply information.

(3-1-2) Consumer Call Next, in FIG. 6, in the power transaction between one supplier and a plurality of consumers, a plurality of facilities B to E (a plurality of first ones on the customer side). A case will be described in which each user of a facility (a consumer of distributed power) makes demand requests (first requests) B to E to start a power transaction. That is, a case where power trading starts with a customer call will be described.

  In FIG. 6, demand requests B to E indicate that the plurality of facilities B to E on the consumer side generate the distributed power generated by one facility A (second facility) on the supplier side, This is a request for requesting supply to the facilities B to E. 6, in the facility A on the supplier side, the demand requests B to D among the demand requests B to E are approved (consent B to D: supply request (second request)), and the facility A on the supplier side. Distributed power is supplied to a plurality of facilities B to D on the consumer side. On the other hand, the demand request E is not accepted by the facility A, and distributed power is not supplied from the facility A to the facility E. That is, a power transaction is performed between one facility A (one second facility) on the supplier side and a plurality of facilities B to D (a plurality of first facilities) on the consumer side. A specific flow will be described below.

  The power transaction method (supplier call) in FIG. 6 differs from the power transaction method (supplier call) in FIG. 3 in that the request for distributed power is a customer call, and in that respect the processing procedure Is different. Therefore, the description of the same processing as in FIG. 3 is simplified.

  Steps S1-1 to S1-4: Each user of the plurality of facilities B to E receives the distributed power generated by the power generator 23A from the input unit (not shown) of the plurality of facilities B to E. Demand requests (first requests) B to E that are requested to be supplied are input. The input is the same as step S1 in FIG. In each facility BE, demand requests BE are input.

  When the distributed power management units 25B to 25E of the facility terminals 21B to 21E (a plurality of first facility terminals) receive the demand requests B to E based on the input contents described above, the distributed power management units 25B to 25E transmit the demand requests B to E to the mediation processing unit 31 of the mediation terminal 30. . The intermediary processing unit 31 refers to the storage unit 15 (FIG. 2) of the management terminal 11, and the facility A and the plurality of facilities B to E about to start the distributed power transaction are registered in the storage unit 15. If so, the process proceeds to step S2.

  Step S2: The mediation processing unit 31 transmits demand requests B to E of a plurality of facilities B to E to the facility A (second facility). The distributed power management unit 25A of the facility terminal 21A (second facility terminal) of the facility A receives the demand requests B to E and presents the demand requests B to E to the user of the facility A via a display unit (not shown), for example. . The user (distributed power supplier) of the facility A receives the demand requests B to E and inputs approval or disapproval to the distributed power management unit 25B through the input unit. In the case of FIG. 6, the user of the facility A accepts the demand requests B to D from the plurality of facilities B to D (acceptance B to D) and does not accept the demand request E from the facility E.

Step S <b> 3: The distributed power management unit 25 </ b> A transmits approvals B to D of demand requests B to D to the mediation processing unit 31. Here, the distributed power management unit 25 </ b> A may transmit a notification of disapproval of the demand request E of the facility E to the mediation processing unit 31.
Steps S4-1 to S4-3: The mediation processing unit 31 transmits notifications of consents BD to the distributed power management units 25B to 25D.
Step S4-4: The mediation processing unit 31 transmits a notification of disapproval to the distributed power management unit 25E based on the absence of the approval notification from the distributed power management unit 25A or the reception of the disapproval notification. .

Steps S5-1 to S5-3: The distributed power management unit 25A supplies the power generation apparatus 23A with distributed power to the facilities B to D based on the information included in the demand requests B to D and the consents BD. Let it be done. The information includes, for example, a supply ratio, and distributed power is distributed as described with reference to FIG.
The surplus distributed power can flow backward to the grid power side. Further, the power shortage at the facilities B to D can be supplemented from the power company 10.

Steps S6-1 and S6-2: Either the power generation device 23A or the distributed power management unit 25A notifies the mediation processing unit 31 of the supply amount of the distributed power from the power generation device 23A.
Step S7-1: The mediation processing unit 31 notifies the distributed power management unit 25A of details regarding the amount of distributed power supplied from the power generation device 23A.
Steps S7-2 to S7-4: The mediation processing unit 31 notifies the distributed power management units 25B to 25D of the details of the received amount based on the supply amount of the distributed power to each of the plurality of facilities B to D. .

(3-1-3) Supplier Call and Customer Call Next, referring to FIG. 7, in a power transaction between one supplier and a plurality of consumers, one facility A (first in the supplier side) (2 facilities) users (distributed power suppliers) make a supply request (second request) A, and each user (distributed power of multiple facilities B-E (plural first facilities) on the consumer side) A case will be described in which a power consumer starts by making demand requests (first requests) B to E by a consumer. That is, a case will be described in which a power transaction starts with a supplier call and a customer call.

  In FIG. 7, the supply request A is a request for one facility A on the supplier side to supply the distributed power generated at the facility A on the supplier side to a plurality of facilities B to D on the customer side. is there. In addition, the demand requests B to E are generated by the plurality of facilities B to E on the consumer side using the distributed power generated by one facility A (second facility) on the supplier side, and the plurality of facilities B on the consumer side. ~ E request to supply to E.

  And the electric power transaction is materialized in the point where the supply request A and the demand requests BE match. In the case of FIG. 7, the demand requests B to E of the facilities B to E are for the facility A, and the supply request A of the facility A is for the facilities B to D. Therefore, the supply request A and the demand requests B to D coincide with each other in terms of power transactions performed between the facilities A and the facilities B to D. That is, a power transaction is performed between one facility A (one second facility) on the supplier side and a plurality of facilities B to D (a plurality of first facilities) on the consumer side. A specific flow will be described below.

  The power transaction method (supplier call and consumer call) in FIG. 7 is an intermediary between the power transaction method (supplier call) in FIG. 3 and the power transaction method (customer call) in FIG. The processing unit 31 receives a supply request and a demand request and determines whether or not to accept the request, and the processing procedure is different in that respect. Therefore, the description of the same processing as in FIGS. 3 and 6 will be simplified.

Steps S1-1 to 1-4: Each user of the plurality of facilities B to E receives the distributed power generated by the power generator 23A from the input unit (not shown) of the plurality of facilities B to E. Demand requests B to E that are requested to be supplied are input.
Step S1-5: The user of the facility A inputs a supply request A for supplying the distributed power generated by the power generator 23A to the plurality of facilities B to D from an input unit (not shown) of the facility A.

  The mediation processing unit 31 receives the supply request A via the distributed power management unit 25A of one facility terminal 21A (one second facility terminal), and a plurality of facility terminals 21B to 21E (a plurality of first facility terminals). Demand requests B to E are received via the distributed power management units 25B to 25E. The intermediary processing unit 31 refers to the storage unit 15 (FIG. 2) of the management terminal 11, and whether or not the facility A and the facilities B to E for which the power transaction of distributed power is about to be started is registered in the storage unit 15. Judging.

  When the facility A and the facilities B to E are registered, the mediation processing unit 31 determines whether the supply request A and the demand requests B to E match. Then, the mediation processing unit 31 performs steps S2-1 to S2-5 based on the determination result.

  Steps S2-1 to S2-4: When the mediation processing unit 31 compares the supply request A with the demand requests B to E and determines that the supply request A and the demand requests B to D match, the distributed power The consent A of the supply request A is transmitted to the management unit 25A (step S2-1). On the other hand, the mediation processing unit 31 transmits approvals B to D of demand requests B to D to the distributed power management units 25B to 25D (steps S2-1 to S2-3).

  Note that the mediation processing unit 31 determines whether the supply request and the demand request match or does not match based on the input content input for each request. For example, the mediation processing unit 31 determines that the requests match when the supply destination and the supply source are related to each other. In the case of FIG. 7, the demand requests B to E of the facilities B to E are for the facility A, and the supply request A of the facility A is for the facilities B to D. Therefore, the mediation processing unit 31 determines that the demand requests B to D and the supply request A coincide with each other in terms of power transactions performed between the facilities A and the facilities B to D. On the other hand, the demand request E is for the facility A, but since the supply request A is not made for the facility E, the mediation processing unit 31 determines that the demand request E and the supply request A do not match. to decide.

Further, the mediation processing unit 31 determines whether each request has a desired unit price that is the same or approximately the same, when the type of power is the same, when the supply time period is approximately the same, etc. It may be determined whether the requests match.
The mediation processing unit 31 determines that the requests are matched if at least the facilities related to the requests are related to each other and at least some of the other points are matched. May be.

  Step S2-5: When determining that the supply request A and the demand request E are inconsistent, the mediation processing unit 31 transmits a disapproval of the demand request E to the distributed power management unit 25E.

Steps S3-1 to S3-3: When the distributed power management unit 25A receives the consent A of the supply request A from the mediation processing unit 31, the distributed power management unit 25A causes the power generation apparatus 23A to perform the determination based on the information included in the supply request A and the consent A. The distributed power is supplied to the facilities B to D. The information includes, for example, a supply ratio, and distributed power is distributed as described with reference to FIG.
The surplus distributed power can flow backward to the grid power side. Further, the power shortage at the facilities B to D can be supplemented from the power company 10.

Steps S4-1 and S4-2: Either the power generation device 23A or the distributed power management unit 25A notifies the mediation processing unit 31 of the supply amount of the distributed power from the power generation device 23A.
Step S5-1: The mediation processing unit 31 notifies the distributed power management unit 25A of the details regarding the amount of distributed power supplied from the power generation device 23A.
Steps S5-2 to S5-4: The mediation processing unit 31 notifies the distributed power management units 25B to 25D of the details of the received amount based on the supply amount of the distributed power to the plurality of facilities B to D and the like.

  In the process of FIG. 7, when the intermediary processing unit 31 receives the supply request A from the facility A and the demand requests B to E from the facilities B to E, the supply request A and the demand requests B to E are matched. Judge to determine whether to accept these requests. However, as in FIG. 3, the mediation processing unit 31 transmits the supply request A from the facility A to the facilities B to D, and inputs whether or not to accept the supply request A from each user of the facilities B to D. May be accepted. Similarly to FIG. 6, the mediation processing unit 31 transmits the demand requests B to E from the facilities B to E to the facility A, and determines whether or not to accept the demand requests B to E from the user of the facility A. Input may be accepted.

(4) Operation According to the power trading method of the power trading system 1 described above, when the demand request (first request) and the supply request (second request) among a plurality of facilities match, Enables distributed power trading between multiple facilities. Therefore, while a plurality of facilities exist in the power trading system 1 capable of receiving the supply of grid power, it is possible to trade distributed power among the facilities and improve the flexibility of power trading. It is.

  As described above, as described above, a supply request (second request) is made from one facility (second facility) on the supply side, and demand requests (a plurality of first facilities) on the demand side, as described above. When a first request is made, a supply request (second request) is made from a plurality of facilities (a plurality of second facilities) on the supply side, and a demand request (one first facility) is made from one facility on the demand side (one first facility). When a first request is made, a supply request (second request) is made from a plurality of facilities (a plurality of second facilities) on the supply side, and a demand request (a plurality of first facilities) is made from a plurality of facilities on the demand side (a plurality of first facilities) The first request is made.

  In addition, for example, a demand request for supplying distributed power from users of a plurality of demand-side facilities B (first facilities) to users of a plurality of supply-side facilities A (second facilities) is possible. On the contrary, there is a supply request for requesting that users of a plurality of supply-side facilities A (second facilities) receive distributed power from users of a plurality of demand-side facilities B (first facilities). Is possible.

  If the requests from both users match, it is possible to satisfy the demand for the supply and demand of distributed power between specific facilities (or individuals). Thereby, even between facilities existing in the power trading system 1 capable of receiving the supply of grid power, for example, it is possible to trade distributed power reflecting the intention among specific individuals, for example. In this case, the degree of freedom in power trading can be improved.

The demand request and the supply request for distributed power include additional conditions such as a desired unit price and a power supply condition indicating the type of power generated by the distributed power. Thereby, it is possible to trade distributed power between facilities existing in the power trading system 1 capable of receiving supply of grid power while limiting power trading according to desired conditions. For example, the desired condition is based on an individual's intention, and power trading with a high degree of freedom reflecting the individual's intention is possible.
