By including facility-related information in the input content, for example, the supplier can specify what kind of facility to supply distributed power to, and the consumer can specify from what kind of facility to receive distributed power. Can be specified.

A supply request is constructed based on these inputs. The input content is not limited to the above-described input content, as long as there is at least information specifying the supply destination. In addition, the input content may also include an environmental coefficient or the like indicating the 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 input contents described above, it transmits the supply request A to the mediation processing unit 31 of the mediation terminal 30 .

The intermediation processing unit 31 refers to the storage unit 15 (FIG. 2) of the management terminal 11 to check whether the facility A and the plurality of facilities B to E with which power trading of distributed power is about to start are registered in the storage unit 15. determine whether or not If the facility A and a plurality of facilities B to E are registered in the storage unit 15, the mediation processing unit 31 advances the process 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 if the facility A and any of the plurality of facilities B to E are 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. Distributed power management units 25B to 25E of facility terminals 21B to 21E (plurality of first facility terminals) of a plurality of facilities B to E receive the supply request A, for example, through a display unit (not shown) to the plurality of facilities B to E. presents a supply request A to each user of .

Each user of the plurality of facilities B to E receives the presentation of the supply request A, and when accepting the supply request A, inputs the acceptance to the distributed power management units 25B to 25E through an input unit (not shown). In the case of FIG. 3, each user of a plurality of facilities B to D has accepted supply request A from facility A. In FIG. Here, acceptances of the supply request A by each user of the plurality of facilities B to D are assumed to be acceptances B to D, respectively. These grants are demand requests for facility A's distributed power by facilities BD.

Acceptance of this supply request includes not only acceptance of all the 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, the desired unit price, the power supply condition indicating the type of power generated by the distributed power, the supply time zone in one day, the period, and whether or not to notify the supplier's personal information. additional conditions are included. Acceptance of supply requests may then be accordable to each of these additional terms.

For example, the user of the facility B can approve the desired unit price and the power supply conditions in the supply request A and only part of the supply time period. In addition, the user of the facility C can also approve only part of the desired unit price, power supply conditions, and period of the supply request A. Thus, the acceptance may include information that the entire supply request is accepted, or information about the accepted portion of the supply request.

When each user of the plurality of facilities B to E receives the supply request A and does not accept the supply request A, they input their disapproval to the distributed power management units 25B to 25E through an input unit (not shown). do.
In the case of FIG. 3, the user of the facility E has entered a disapproval of the supply request A into 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 approvals B to D for the supply request A to the mediation processing unit 31.
Step S3-4: On the other hand, the distributed power management unit 25E transmits a disapproval to the supply request A to the mediation processing unit 31.

Step S4: The intermediation processing unit 31 transmits notifications of consents B to D to the distributed power management unit 25A.
Although not shown in FIG. 3, the mediation processing unit 31 may transmit a disapproval to the supply request A from the distributed power management unit 25E to the distributed power management unit 25A. Based on the fact that the distributed power management unit 25A has not received acceptance of the supply request A from the facility E, or based on the fact that it has received the disapproval of the supply request A from the facility E, the distributed power management unit 25A receives the power generation device 23A from the facility E control so as not to supply distributed power to

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

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

Alternatively, 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 BD based on the determined supply ratio. Further, the mediation processing unit 31 may notify the facilities B to D to receive power supply based on the determined supply ratio.
The method of determining the supply ratio is not particularly limited, but the intermediation processing unit 31 may determine, for example, based on the contents of consents B to D to supply request A by users of facilities B to D.

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

If the distributed power generated by the power generation device 23A can sufficiently satisfy the demand for the distributed power of each of the facilities B to D, the mediation processing unit 31 does not need to determine the supply ratio. 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 sufficient state. In this case, each of the facilities B to D receives the required amount of power from the electric power company 10 .

Step S5-2: The power generator 23A determines that surplus distributed power is generated when the distributed power generated by itself is greater than the distributed power supplied to the plurality of facilities BD. In this case, for example, the power generator 23A reversely flows surplus distributed power to the electric power company 10, for example.

Here, facility A and a plurality of facilities B to D are included in power trading system 1 capable of receiving grid power supply from power company 10 . Therefore, as described above, of the distributed power generated by the power generation device 23A of the facility A, surplus distributed power remaining after the distributed power is supplied from the facility A to the plurality of facilities B to D can be reversely flowed to the grid power side. is. As a result, the efficient use of the surplus distributed power can be promoted by causing the surplus distributed power to reversely flow while preferentially supplying the distributed power to specific facilities.

Step S5-3: The distributed power generated by the power generator 23A may be less than the distributed power supplied to the plurality of facilities BD. In this case, for example, the facilities B to D are supplied with 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 trading system 1 capable of receiving grid power supply from the power company 10, as described above, the shortage of power is can compensate. As a result, the demand for electric power at the facility B can be satisfied in general just the right amount.

Step S6-1: The power generator 23A notifies the distributed power management unit 25A of the amount of distributed power supplied to the plurality of facilities BD. In this case, the power generator 23A may notify the distributed power management unit 25A of the surplus distributed power amount reversely flowed to the power supplier 10 .
Step S6-2: The distributed power management unit 25A notifies the mediation processing unit 31 of the amount of distributed power supplied to the plurality of facilities B to D.

It should be noted that the power generation device 23A may notify the intermediary processing unit 31 of the amount of power supplied 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 to the plurality of facilities BD.

Step S7-1: The intermediation processing unit 31 notifies the distributed power management unit 25A of the details of the amount of distributed power supplied, based on the amount of distributed power supplied from the power generator 23A to the plurality of facilities BD. Here, the unit price of the distributed power is, for example, the 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 intermediation processing unit 31 notifies the distributed power management units 25B to 25D of each detail of the received amount based on the amount of distributed power supplied to each of the plurality of facilities B to D. .

The distributed power management units 25B to 25D present each item to each user of the facilities BD via a display unit (not shown). Each user of facilities B to D is presented with the details shown in FIG. 5, for example. FIG. 5 shows, for example, a monthly statement for October, and shows the power supply composition ratio, purchase unit price, purchase amount, and the like for each supply source. The power supply composition ratio indicates the ratio of each type of power, including power generated by photovoltaic power generation, power generated by wind power generation, and power generated by a fuel cell system, with respect to supplied power. The details may also include an environmental coefficient indicating the load on the environment, and a supply time period of distributed power.

FIG. 5 shows an example of the details of each user (electricity consumer) of facilities B to D, but in step S7-1, the same applies to the user of facility A (electricity supplier). Details may be provided.
In this way, the details are transmitted as distributed power supply information to each facility terminal between facilities with which distributed power is traded. Users of the facility can confirm supply information.

(3-1-2) Demander call facility) users (distributed power consumers) make demand requests (first requests) B to E to start power trading. In other words, a case will be described where electricity trading starts with a call from a consumer.

In FIG. 6, demand requests B to E are distributed power generated at one facility A (second facility) on the supplier side by a plurality of facilities B to E on the demand side, This is a request to ask facilities B to E to supply. In FIG. 6, demand requests B to D out of demand requests B to E are accepted (acceptance B to D: supply requests (second requests)) at facility A on the supplier side. distributed power is supplied to a plurality of facilities B to D on the demand side. On the other hand, demand request E is not granted at facility A, and facility A does not supply distributed power to facility E. In other words, power trading is performed between one facility A (one second facility) on the supplier side and a plurality of facilities BD (a plurality of first facilities) on the consumer side. A specific flow will be described below.

The power trading method (supplier call) in FIG. 6 differs from the power trading method (supplier call) in FIG. 3 in that the demand for distributed power is a consumer call. is different. Therefore, the description of the processing similar to that of FIG. 3 will be simplified.

Steps S1-1 to S1-4: Each user of a plurality of facilities B to E transmits the distributed electric power generated by the power generation device 23A to the facilities B to E from the input units (not shown) of the plurality of facilities B to E. Enter the demand request (first request) BE that requests to supply to Input is the same as step S1 in FIG. Demand requests B to E are input to the facilities B to E, respectively.

When the distributed power management units 25B to 25E of the facility terminals 21B to 21E (plurality of first facility terminals) receive the demand requests B to E based on the input content described above, they transmit the requests to the mediation processing unit 31 of the mediation terminal 30. . The intermediation 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 with which power trading of distributed power is about to start 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, for example, a display unit (not shown). . A user of the facility A (distributed power supplier) receives the presentation of 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 facility A has accepted demand requests B to D from a plurality of facilities B to D (acceptance B to D), but has not accepted demand request E from facility E. In FIG.

Step S3: The distributed power management unit 25A transmits the approvals B to D of the demand requests B to D to the mediation processing unit 31. Here, the distributed power management unit 25A may transmit a notice of non-acceptance of the demand request E of the facility E to the mediation processing unit 31 .
Steps S4-1 to S4-3: The intermediation processing unit 31 transmits notifications of acceptance B to D 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 fact that there is no notification of consent from the distributed power management unit 25A or the notification of disapproval is received. .

Steps S5-1 to S5-3: The distributed power management unit 25A causes the power generator 23A to supply distributed power to the facilities B to D based on the information included in the demand requests B to D and the approvals B to D. let it happen Said information includes, for example, the supply rate and distributed power is distributed as explained in FIG.
In addition, the surplus distributed power can be reversely flowed to the grid power side. Further, power shortages at facilities B to D can be replenished by the electric 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 amount of distributed power supplied from the power generation device 23A.
Step S7-1: The mediation processing unit 31 notifies the distributed power management unit 25A of the details of the amount of distributed power supplied from the power generator 23A.
Steps S7-2 to S7-4: The intermediation processing unit 31 notifies the distributed power management units 25B to 25D of each detail of the received amount based on the amount of distributed power supplied to each of the plurality of facilities B to D. .

(3-1-3) Supplier call and consumer call 2 facilities) user (distributed power supplier) makes a supply request (second request) A, and each user of multiple facilities B to E (multiple first facilities) on the demand side (distributed power supply A case will be described where power trading starts when a consumer) makes demand requests (first requests) B to E. In other words, a case will be described where power trading starts with a call from a supplier and a call from a consumer.

In FIG. 7, a supply request A is a request from one facility A on the supplier side to supply distributed power generated at the facility A on the supplier side to a plurality of facilities B to D on the consumer side. be. In addition, demand requests B to E are for a plurality of demander-side facilities B to E to supply distributed power generated in one supplier-side facility A (second facility) to a plurality of demander-side facilities B It is a request to ask to supply ~E.

At the point where the supply request A and the demand requests B to E match, the power transaction is established. In the case of FIG. 7, demand demands B to E of facilities B to E are for facility A, and supply demands A of facility A are for facilities B to D. In FIG. Therefore, the supply request A and the demand requests B to D are identical in terms of power transactions between the facility A and the facilities B to D. In other words, power trading is performed between one facility A (one second facility) on the supplier side and a plurality of facilities BD (a plurality of first facilities) on the consumer side. A specific flow will be described below.

The power trading method (supplier calling and consumer calling) in FIG. 7 is different from the power trading method (supplier calling) in FIG. 3 and the power trading method (demander calling) in FIG. The difference is that the processing unit 31 receives the supply request and the demand request and determines whether or not to accept them, and the processing procedure differs in this 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 a plurality of facilities B to E transmits distributed electric power generated by the power generation device 23A to a plurality of facilities B to E from input units (not shown) of the plurality of facilities B to E. Enter the demand requests B through E that are required to be supplied to
Step S1-5: The user of the facility A inputs a supply request A for supplying distributed power generated by the generator 23A to a plurality of facilities BD from the input unit (not shown) of the facility A.

The intermediation 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 receives the supply request A from 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 brokerage processing unit 31 refers to the storage unit 15 (FIG. 2) of the management terminal 11, and determines whether the facility A and the facilities B to E with which power trading of distributed power is about to start are registered in the storage unit 15. to judge.

When the facility A and the facilities B to E are registered, the mediation processing unit 31 determines whether or not the supply request A and the demand requests B to E match. Then, the intermediation processing section 31 performs the processing of steps S2-1 to S2-5 based on the determination result.

Steps S2-1 to S2-4: The intermediary processing unit 31 compares the supply request A with the demand requests B to E, and if it determines that the supply request A and the demand requests B to D match, An acceptance A of the supply request A is sent to the management section 25A (step S2-1). On the other hand, the intermediation processing unit 31 transmits acceptances B to D of the 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 disagree based on the input content input for each request. For example, when the supply destination and the supply source are related to each other, the mediation processing unit 31 determines that each request matches. In the case of FIG. 7, demand demands B to E of facilities B to E are for facility A, and supply demands A of facility A are for facilities B to D. In FIG. Therefore, the intermediary processing unit 31 determines that the demand requests B to D and the supply request A are identical in terms of power transactions between the facility A and the facilities B to D. On the other hand, the demand request E is for the facility A, but the supply request A is not for the facility E. to decide.

In addition, the mediation processing unit 31 determines whether the desired unit price of each request matches or is substantially the same, when the type of power is the same, or when the supply time period is substantially the same. It may be determined whether the requests match.
The intermediary processing unit 31 determines that the requests match when at least the facilities related to the requests are related to each other, and when at least a part of the other points match. may

Step S2-5: When the mediation processing unit 31 determines that the supply request A and the demand request E do not match, it 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 approval A of the supply request A from the mediation processing unit 31, based on the information included in the supply request A and the approval A, , to supply distributed power to facilities B to D. Said information includes, for example, the supply rate and distributed power is distributed as explained in FIG.
In addition, the surplus distributed power can be reversely flowed to the grid power side. Further, power shortages at facilities B to D can be replenished by the electric 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 amount of distributed power supplied from the power generation device 23A.
Step S5-1: The mediation processing unit 31 notifies the distributed power management unit 25A of the details of the amount of distributed power supplied from the power generator 23A.
Steps S5-2 to S5-4: The intermediation processing unit 31 notifies the distributed power management units 25B to 25D of the details of the amount of received power based on the amount of distributed power supplied to the plurality of facilities B to D.

In the processing of FIG. 7, when the mediation 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. judgment to determine whether to grant 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 approve the supply request A from each user of the facilities B to D. may be accepted. 6, the intermediary processing unit 31 transmits demand requests B to E from facilities B to E to facility A, and asks users of facility A whether or not to accept demand requests B to E. Input may be accepted.
