Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. In the drawings, the same elements are denoted by the same reference numerals, and redundant description will be omitted as necessary for the sake of clarity.

<Embodiment 1>
FIG. 1 is a block diagram showing an overall configuration including the power distribution management system 15 according to the first embodiment of the present invention. The electric power supplier and demander 11 is a group of equipment that can perform supply and demand of electric power. The electric power supplier and demander 11 is owned and used by the user A. The power supplier and demander 11 includes at least a power storage device 111 and a management terminal 112. In addition, the electric power supplier and demander 11 may include a load (personal house, building, factory, etc.) for consuming electric power and a power generation facility (a solar power generation panel, a wind power generator, etc.) as a configuration (not shown).

The power storage device 111 is an example of a power storage facility, and is a device that stores supplied power. The management terminal 112 is operated by the user A and controls discharge for storing power in the power storage device 111, consuming power in the power supplier 11, supplying power to the outside, and the like. In addition, the management terminal 112 makes a power transaction request, a virtual power registration request, and the like as described later to the power distribution management device 152 by the operation of the user A. The management terminal 112 is realized by, for example, a general-purpose computer device and an input / output device.

The power supplier and demander 12 is a group of equipment that can supply and receive power in the same manner as the power supplier and demander 11. It is owned and used by the electric power supplier and demander 12 user B. The power supplier and demander 12 includes a power storage device 121 and a management terminal 122 and has the same configuration as the power supplier and demander 11.

The power suppliers and

demanders

11 and 12, the on-demand power transmission system 14, and the surplus power storage device 151 are connected via the power network 13 and can transmit / receive power to / from each other. Here, the on-demand power transmission system 14 receives a power transmission instruction for a specified amount of power from the power transmission source to the power transmission destination via the communication network 16, and each power storage device etc. via the power network 13 based on the power transmission instruction. Controls the transmission of power between. Note that since the on-demand power transmission system 14 can use a known system, detailed description thereof is omitted.

The power transaction price management system 17 is connected to the power distribution management device 152 and the like via the communication network 16. The power transaction price management system 17 manages the latest transaction price of power based on the specified power generation method and power generation region. The power transaction price management system 17 can use a known information system, and thus a detailed description thereof is omitted.

The power distribution management system 15 is an information system for managing power distribution such as power transactions and power transmission / reception among a plurality of power suppliers and demanders including

power suppliers

11 and 12 and power companies. The power distribution management device 152 and the surplus power storage device 151 are provided. The surplus power storage device 151 is a device that stores surplus power to be supplied to the

power suppliers

11 and 12. Here, it is assumed that the surplus power storage device 151 stores at least surplus power equal to or greater than the virtual power amount described below. The surplus power storage device 151 may be built in the power distribution management device 152.

FIG. 2 is a block diagram showing a configuration of the power distribution management device 152 according to the first embodiment of the present invention. The power distribution management device 152 includes a storage unit 21, a registration unit 22, a determination unit 23, an update unit 24, a power transmission instruction unit 25, and a power storage unit 26. The storage unit 21 is a storage device that stores surplus power management information 211 and user power management information 212. The surplus power management information 211 is information for managing the breakdown of the amount of power stored in the surplus power storage device 151.

FIG. 3 is a diagram showing an example of surplus power management information 211 according to the first embodiment of the present invention. Here, it is assumed that a total amount of power of 1300 kWh is stored in surplus power storage device 151. The surplus power management information 211 indicates that the owner, the user type, the power generation method, and the power generation area are managed as a breakdown of the amount of power stored in the surplus power storage device 151. However, the surplus power owner is a “system”, that is, the power distribution management system 15 in principle, and indicates that it is not the user A or B. Here, the “real power” of the power type indicates that the corresponding power amount is an actual power amount. The power generation method indicates whether the corresponding amount of power is generated by, for example, photovoltaic power generation (PV (Photovoltaics)), nuclear power generation, thermal power generation, or the like. The power generation region indicates in which region the corresponding amount of power is generated.

For example, # 1 in FIG. 3 indicates that 100 kWh of the amount of power stored in the surplus power storage device 151 is real power and is generated in PV in the XX prefecture. The power generation method and the power generation area are examples of power attribute information. Therefore, the power attribute information includes the name of the power plant, the individual of the supplier, the power company, and the like.

User power management information 212 is information for managing a breakdown of the amount of power owned by each user. Here, it is assumed that the amount of power owned by each user can be real power and virtual power as power types. The actual power indicates the actual amount of power stored in the

power storage device

111 or 121. The virtual power indicates that the corresponding power amount is not stored in the

power storage device

111 or 121 but is assumed to be owned by the user (virtual power amount). The virtual power amount indicates that the user who owns the power is scheduled to be procured by a predetermined time. In other words, the virtual power is power that can be supplied to the user or other users by replacing the power scheduled to be procured in the future by the system with surplus power. Therefore, a user who does not own real power can own only virtual power and buy and sell virtual power for distribution. The user power management information 212 can be said to be information in which a user is associated with either the actual power amount or the temporary power amount. Furthermore, it can be said that the attribute information is associated with the actual power amount or the temporary power amount.

FIG. 4 is a diagram showing an example of user power management information according to the first exemplary embodiment of the present invention. Here, it is shown that the user A owns the actual power amount of 30 kWh and the total temporary power amount of 100 kWh, 130 kWh, and the user B owns the actual power amount of 20 kWh. In particular, 30 kWh of the amount of power owned by the user A is the actual amount of power actually stored in the power storage device 111 and indicates that the power is generated in the XX prefecture. In addition, 100 kWh of the amount of power owned by user A is not currently owned as real power (at least not stored in power storage device 111), but the user A does not have sunlight in YY prefecture by a predetermined time. Indicates that the amount of power generated is procured.

Referring back to FIG. In response to the user's registration request, the registration unit 22 sets the specified power amount as the temporary power amount, and registers it in the storage unit 21 as the user power management information 212 in association with the specified user. The determination unit 23 determines whether or not the power amount of the user power management information 212 satisfies the required power amount when receiving a power transmission request in which the required power amount is specified. Here, the determination unit 23 determines whether there is a power amount that satisfies each condition specified in the power transmission request. Each condition includes, for example, designation of a user of a power transmission source (here, an owner), a power type, a power generation method, a power generation region, and the like.

The update unit 24 updates the user power management information 212 according to the determination result by the determination unit 23. In addition, the update unit 24 updates the surplus power management information 211 and the user power management information 212 in response to power storage and discharge in the

power storage devices

111 and 121 and the surplus power power storage device 151, that is, power transmission and power reception. .

The power transmission instruction unit 25 transmits, to the on-demand power transmission system 14, a power transmission instruction that specifies the power storage device that is the power transmission source, the power storage device that is the power transmission destination, and the amount of power to be transmitted according to the determination result by the determination unit 23. . In particular, when the virtual power amount is included in the power amount determined to satisfy the condition as the determination result, the power transmission instruction unit 25 instructs the power transmission for the virtual power amount as the surplus power power storage device 151. I do.

The power storage unit 26 stores the power received via the power network 13 in the surplus power storage device 151. In particular, the power storage unit 26 receives and stores the power amount procured by the original owner of the virtual power for the power amount transmitted instead of the virtual power amount.

FIG. 5 is a flowchart showing the flow of the virtual power registration process according to the first embodiment of the present invention. For example, it is assumed that the user A currently stores only 30 kWh procured by thermal power generation in the power storage device 111 he owns, but plans to procure 100 kWh by solar power generation in YY within one month. In such a case, the management terminal 112 transmits, to the power distribution management device 152, a virtual power registration request designating the power amount 100 kWh, solar power generation, and the power generation area YY prefecture by the operation of the user A. The registration unit 22 of the power distribution management device 152 receives a registration request from the management terminal 112 via the communication network 16 (S11). Then, the registration unit 22 registers the user power management information 212 in the storage unit 21 as the virtual power amount of the user A based on the specified content of the registration request (S12). The attribute information is also registered together with the electric energy. For example, the power ID “2” in FIG. 4 is registered. In addition, when the real power is also stored in each of the

power storage devices

111 and 121, the registration unit 22 also associates attribute information with the power amount of each user who owns the power storage device as the user power management information 212. Register in the storage unit 21. For this reason, in the real power storage, the supply source notifies the power distribution management device 152 of the attribute information of the power to be supplied.

FIG. 6 is a flowchart showing the flow of the power distribution process according to the first embodiment of the present invention. First, the determination unit 23 receives a power transaction request specifying a predetermined condition for the user A from the user B (the management terminal 122 operated by the user B) (S21). That is, the determination unit 23 receives a power transmission request (power transaction request) for transmitting power from the user A to the user B. It is assumed that at least the required power amount is specified as the predetermined condition. Furthermore, attribute information in the required power amount, for example, a power generation method, a power generation region, or the like may be specified as a predetermined condition. Next, the determination unit 23 determines whether or not the user A owns power that satisfies the condition (S22). That is, the determination unit 23 refers to the power amount of the user A in the user power management information 212 of the storage unit 21 and compares it with the required power amount.

When it is determined in step S22 that the user A owns power that satisfies the condition, the power distribution management device 152 uses the communication transaction 16 to determine the latest transaction price of the power that satisfies the specified condition. Obtained from the management system 17 (S23). Then, the transaction price is presented from the user A to the user B (S24), and a sales contract for a power transaction is attempted. In step S24, the power distribution management device 152 relays negotiations of prices and conditions between the

management terminals

112 and 122.

Thereafter, when a sales contract is established (YES in S25) and the power transmission target is real power (in the case of real power in S26), the power transmission instruction unit 25 transfers from the power storage device 111 of the user A to the power storage device 121 of the user B. An instruction to transmit specified power is given to the on-demand power transmission system 14. In addition, the update unit 24 updates the user power management information 212 (S27).

On the other hand, when a sales contract is established (YES in S25) and the power transmission target is virtual power (in the case of virtual power in S26), the power transmission instruction unit 25 designates the surplus power power storage device 151 to the power storage device 121 of the user B. Is directed to the on-demand power transmission system 14. In addition, the update unit 24 updates the surplus power management information 211 and the user power management information 212 (S28).

If it is determined in step S22 that the user A does not own power satisfying the condition, or if the sales contract is not established in step S25, the power distribution management device 152 indicates that the user B cannot perform the transaction. A response is sent to the management terminal 122 (S29).

Subsequently, the virtual power transaction and power transmission processing will be described with specific examples. FIG. 7 is a sequence diagram showing the flow of the virtual power transaction and the power transmission process according to the first embodiment of the present invention. Here, it is assumed that the surplus power management information 211 and the user power management information 212 are in the states of FIGS. 3 and 4 described above, respectively.

First, the user B transmits an 80 kW power transaction request by PV to the user A to the power distribution management device 152 by the management terminal 122 (S301). Then, the determination unit 23 refers to the user power management information 212 of the storage unit 21 and confirms the amount of power owned by the user A (S302). In other words, the determination unit 23 determines whether or not the virtual power amount of the user A satisfies the required power amount when receiving the power transmission request in which the required power amount for transmitting power from the user A to the user B is received. . In addition, the determination unit 23 determines whether or not the attribute information associated with the virtual power amount of the user A satisfies the power generation method “PV” specified in the power transmission request. Here, the determination unit 23 cannot satisfy the transaction request with the real power of the user A (power ID “1” in FIG. 4), but can satisfy the transaction request with virtual power (power ID “2” in FIG. 4). Is determined.

Then, the power distribution management device 152 transmits an inquiry about the latest transaction price of PV power to the power transaction price management system 17 (S303). Then, the power transaction price management system 17 returns the transaction price corresponding to the condition as a reply to the power distribution management device 152 (S304). The power distribution management device 152 does not necessarily have to make an inquiry to the power transaction price management system 17. For example, the power distribution management device 152 may independently set the transaction price based on the power amount, the power type, the power generation method, and the power generation area.

The power distribution management device 152 notifies the transaction price to the management terminal 112 of the user A (S305). Then, the user A determines a transaction price to be presented to the user B, and notifies the determined transaction price (present price) from the management terminal 112 to the management terminal 122 via the communication network 16 and the power distribution management device 152 (S306). ). At this time, the user A may determine the acquired transaction price as the suggested price as it is, or may appropriately determine the suggested price by adding a fee or a predetermined discount. Furthermore, the user A may notify the offer price under a condition in which the condition from the user B is partially changed. For example, instead of using part of the power to be traded as electric power generated by thermal power generation, a discount price may be presented as compared with the case where the whole is PV. It should be noted that the determination of the suggested price or the change of conditions may be processed by the power storage device 121 or the power distribution management device 152.

Thereafter, the user B notifies the power distribution management device 152 (and the management terminal 122) from the management terminal 122 via the communication network 16 that the offer price has been accepted (S307). As a result, it is assumed that a sales contract is established.

In response, the update unit 24 updates 80 kWh of the virtual power amount of the user A to be owned by the user B (S308). Specifically, as shown in FIG. 8, the power amount of the power ID “2” is updated from 100 to 20, and information that the user B owns the virtual power 80 kWh is added to the storage unit 21 as the power ID “4”. To do. In other words, the updating unit 24 associates the second virtual power amount corresponding to the required power amount (80 kWh) out of the first virtual power amount (user A's virtual power amount 100 kWh) with user B (FIG. 8). Power ID “4”), the first virtual power amount minus the second virtual power amount (20 kWh) as the first virtual power amount (power ID “2” in FIG. 8), and the storage unit 21 is updated. Thus, even if 80 kWh by PV is not stored as real power in the power storage device 111, the user A buys and sells the right to supply power to the user B by using the virtual power registration information. be able to.

And the power transmission instruction | indication part 25 performs the instruction | indication which transmits surplus electric power to the user B (S309). That is, the power transmission instruction unit 25 issues a power transmission instruction to the on-demand power transmission system 14 to transmit a power amount corresponding to the required power amount from the surplus power power storage device 151 to the power storage device 121 owned by the user B.

The on-demand power transmission system 14 instructs the surplus power power storage device 151 to transmit 80 kWh toward the power storage device 121 according to the power transmission instruction in step S309 (S310). Then, the surplus power power storage device 151 transmits 80 kWh of power to the power storage device 121 via the power network 13 in response to the power transmission instruction (S311). Thereafter, the on-demand power transmission system 14 transmits a power transmission completion report to the power distribution management device 152 (S312). Thus, by replacing the power amount corresponding to the virtual power amount with the surplus power, the real power can be promptly supplied to the user B who is the purchaser of the virtual power. That is, even if the real power is insufficient like the user A, the real power can be sold and distributed.

After step S312, the update unit 24 updates the power type of the user B from virtual power to real power (S313). That is, after the amount of power corresponding to the required power amount is stored in the power storage device 121 owned by the user B, the update unit 24 updates the storage unit 21 using the second virtual power amount as the actual power amount. For example, the power type is updated from the virtual power to the actual power as the power ID “4” in FIG. In this way, the actual power and the power management information can be matched.

Thereafter, the user A procures 100 kWh of electric power generated by solar power generation in the YY prefecture by a predetermined time, and transmits it to the surplus power storage device 151. For example, the power generated by the solar power generation panel owned by the user A (installed in YY prefecture) is transmitted to the surplus power storage device 151 via the power network 13. Alternatively, the user A may purchase an amount of power generated by solar power generation in an YY prefecture from an external power company or an individual and transmit the power to the surplus power storage device 151. In any case, the power storage unit 26 stores the amount of power of 100 kWh procured by the user A in the surplus power storage device 151. In this case, the update unit 24 updates the power type of the power ID “2” in FIG. 9 from virtual power to actual power. In this way, the amount of power that the user A has registered in advance as virtual power can be supplemented with the actual power.

In step S308 in FIG. 7, the updating unit 24 satisfies the attribute in which the first virtual power amount satisfies the required power amount and the attribute information associated with the first virtual power amount is specified in the power transmission request. It can be said that the update is performed when the determination unit 23 determines that the information is satisfied. Therefore, by specifying attribute information in the power transmission request, it is possible to meet various needs of the requesting user.

Note that the user A may purchase virtual power from the power distribution management system 15 or an external power company or an individual.

In the first embodiment, the user A can register virtual power in advance by promising (contracting) a predetermined amount of power to the power distribution management system 15 by a predetermined time. . Therefore, user A does not own real power that satisfies the request at the time of a transaction request from user B, but can sell surplus power corresponding to virtual power to user B, so sell power. Can do.

As described above, the first embodiment can deal with various electric power transactions, and can also activate the electric power transaction market. In addition, it is possible to save electricity between individuals and to take in and out on demand, and to realize buying and selling of electricity and gifts to others.

<Embodiment 2>
The second embodiment is a modification of the first embodiment described above, in which a shortage of power is procured with virtual power when a transaction is requested. The overall configuration including the power distribution management system 15 according to the second embodiment and the internal configuration of the power distribution management device 152 are the same as those in FIG. 1 and FIG.

FIG. 10 is a flowchart showing the flow of the power transmission target determination process according to the second embodiment of the present invention. In FIG. 10, the acquisition and presentation of the transaction price and the sales contract in steps S23 and S24 in FIG. 6 are omitted. In addition, here, it is assumed that the surplus power management information 211 and the user power management information 212 are in the states of FIGS. 3 and 11 described above, respectively.

First, the determination unit 23 receives a transaction request in the same manner as Step S21 in FIG. Next, the determination unit 23 determines whether or not the actual power amount of the user A is greater than or equal to the required power amount (S221). That is, the determination unit 23 requests the amount of power (for example, 30 kWh of the power ID “1” in FIG. 11) that the user A owns and the power type is real power in the user power management information 212 of the storage unit 21. It is determined whether or not it is equal to or greater than the electric energy. If the actual power amount of user A is greater than or equal to the required power amount in step S221, the power transmission instruction unit 25 instructs transmission of only the actual power amount of user A (S222). In addition, the update unit 24 updates the storage unit 21 for the user power management information 212 before and after the power transmission instruction.

When the real power amount of the user A is less than the required power amount in step S221, the determination unit 23 determines whether the sum of the real power amount of the user A and the initial virtual power amount is equal to or greater than the required power amount (S223). ). For example, when the required power amount is 70 kWh, the determination unit 23 determines that the first virtual power amount (power ID in FIG. 11) when the first actual power amount (30 kWh) does not satisfy the required power amount (70 kWh). It is determined whether or not “2” (50 kWh) satisfies the remaining amount (40 kWh) obtained by subtracting the first actual power amount from the required power amount.

If the total is equal to or greater than the required power amount in step S223, the power transmission instruction unit 25 instructs the user A to transmit the actual power amount and the virtual power amount (S224). In addition, the update unit 24 updates the storage unit 21 for the user power management information 212 before and after the power transmission instruction. In other words, when the determination unit 23 determines that the first virtual power amount satisfies the remaining amount, the update unit 24 associates the first actual power amount with the user B instead of the user A, and determines the remaining amount. The storage unit 21 is updated with the second virtual power amount associated with the user B and the remaining amount as the first virtual power amount. Therefore, even if the actual power amount is insufficient at the time of requesting power transmission, the virtual power amount and the actual power amount can be added together and supplied.

When the sum of the real power amount of user A and the initial virtual power amount is less than the required power amount in step S223, the registration unit 22 uses the virtual power amount to calculate the shortage power amount according to the user A registration request. Procures (S225). For example, when the required power amount is 100 kWh, it is determined that the total (80 kWh) of the real power amount of user A and the initial virtual power amount is less than the required power amount. At this time, the power distribution management device 152 notifies the user A's management terminal 112 of the insufficient power amount (20 kWh). When the registration request from the management terminal 112 is received, the registration unit 22 registers the user power management information 212 in which the shortage amount of power is the virtual power amount in the storage unit 21.

And the determination part 23 determines whether the sum total of the real electric energy of the user A, the original virtual electric energy, and the procured virtual electric energy is more than request electric energy (S226). For example, in the case of the above example, it is determined that the total of the actual power amount of user A, the initial virtual power amount, and the procured virtual power amount is equal to or greater than the required power amount. Therefore, the power transmission instruction unit 25 instructs the user A to transmit the actual power amount (30 kWh) and the virtual power amount (50 + 20 kWh) (S227). In addition, the updating unit 24 updates the storage unit 21 for the user power management information 212 before and after the power transmission instruction (FIG. 12). In other words, NO in step S223, YES in S225, S226, and S227. In other words, when the determination unit 23 determines that the first virtual power amount does not satisfy the remaining amount, the update unit 24 responds to the user A registration request. Accordingly, the third virtual power amount (20 kWh) that satisfies the remaining amount is registered in the storage unit 21 in association with the user B. At the same time, the power amount corresponding to the actual power amount is transmitted from the power storage device 111 to the power storage device 121, and the power amount corresponding to the virtual power amount is transmitted from the surplus power power storage device 151 to the power storage device 121. Therefore, even if the actual power amount (and the virtual power amount registered in advance) is insufficient at the time of the power transmission request, the required power amount can be supplied by procuring the virtual power amount at that time. .

If the total is less than the required power amount in step S226, the same processing as step S29 in FIG. 6 is performed.

In the above description, the user A previously possesses virtual power at the time of the power transmission request. However, the second embodiment does not own virtual power in advance and also procure virtual power when requested. Applicable.

<Embodiment 3>
In the third embodiment, a case where a request period is specified in a power transmission request and power is divided and transmitted within the request period will be described. FIG. 13: is a block diagram which shows the structure of the electric power distribution management apparatus 152a concerning Embodiment 3 of this invention. The power distribution management device 152a further stores power transmission management information 213 in the storage unit 21 as compared to FIG. Further, the determination unit 23, the update unit 24, and the power transmission instruction unit 25 are appropriately changed as described below. The power transmission management information 213 is information for managing alternative power transmission with surplus power for virtual power and compensation of actual power for virtual power to the surplus power power storage device 151. The power transmission management information 213 manages the power transmission source, power transmission destination, power amount, power ID, and state.

FIG. 15 is a diagram illustrating examples of the user power management information 212 and the power transmission management information 213 according to the third embodiment of the present invention. The user power management information 212 indicates that the user A owns 25 kWh as real power and 25 kWh as virtual power. The power transmission ID “1” of the power transmission management information 213 is the power of 25 kWh from the user A to the system (surplus power storage device 151) for the virtual power of the power ID “2” that is the virtual power registered in the user power management information 212. The amount is set to be compensated by April 30, 2015. Thereby, it is possible to manage the compensation status of the amount of power registered as virtual power by the actual power.

FIG. 14 is a flowchart showing the flow of the power distribution process according to the third embodiment of the present invention. First, the determination unit 23 receives, from the user B (the management terminal 122 operated by the user), a power transaction request for the user A specifying the required power amount and the request period (S401). For example, it is assumed that the required power amount is 100 kWh and the request period is four months from March 2015 to June 2015.

Next, the determination unit 23 determines a plurality of divided periods by dividing the request period into a predetermined number (S402). For example, it is assumed that the request period is divided into four on a monthly basis. Then, the determination unit 23 calculates a plurality of divided power amounts obtained by dividing the required power amount for each of a plurality of divided periods (S403). For example, the required power amount 100 kWh is divided into four, and 25 kWh is set as the divided power amount in each month. Thereafter, the determination unit 23 determines whether or not the actual power amount of the user A satisfies the divided power amount (S404).

When the actual power amount of user A satisfies the split power amount, the power transmission instruction unit 25 transmits the split power amount (25 kWh) from the power storage device 111 to the power storage device 121 in the most recent period (March 2015) among the plurality of split periods. ) Is transmitted (S405). Accordingly, the updating unit 24 updates the actual power amount (25 kWh) of the user A in association with the user B (power ID “1” in FIG. 16). Therefore, it is possible to transmit at least one divided power amount by the most recent period.

In addition, the update unit 24 sets each period (April 2015, May, June) after the most recent period as a deadline, and associates the virtual power amount (25 kWh) corresponding to the divided power amount with the user B. (S406). For example, the updating unit 24 updates the user with the power ID “2” in FIG. 16 from A to B, and adds the power transmission ID “2”. Also, power IDs “3” and “4” and power transmission IDs “3” to “6” in FIG. 16 are added. At this time, the power transmission deadline of the power transmission ID “2” is April 30, 2015, the power transmission deadline of the power transmission IDs “3” and “4” is May 31, 2015, and the power transmission of the power transmission IDs “5” and “6” is performed. The deadline is June 30, 2015. Thereby, a power transmission time limit is set for each divided period.

After that, when the next time limit arrives, the power transmission instruction unit 25 transmits the power amount corresponding to one divided power amount (25 kWh) from the surplus power power storage device 151 to the power storage device 121 by the next time limit. (S408). In addition, the updating unit 24 updates the transmitted temporary power amount to the actual power amount (S409). Thereafter, it is determined whether or not it is the last time limit. If it is not the last time limit, the process returns to step S407. For example, power transmission is performed before each power transmission deadline, and as shown in FIG. 17, the update unit 24 transmits the state of the power transmission IDs “2”, “4”, and “6” in the power transmission management information 213 from untransmitted power transmission. And the power types of the power IDs “2”, “3”, and “4” in the user power management information 212 are also updated from virtual power to actual power. In addition, the power storage unit 26 stores, in the surplus power storage device 151, each power amount corresponding to the divided power amount procured by the user A before each deadline after the most recent period. In accordance with this, the update unit 24 updates the state of the power transmission IDs “1”, “3”, and “5” in the power transmission management information 213 from untransmitted to transmitted power, as shown in FIG.

If the actual power amount of user A does not satisfy the divided power amount in step S404, the process is terminated, or virtual power is registered as in the second embodiment, and the processes after step S405 are performed. You can proceed.

In this way, when the request period is specified in the power transmission request, even if not all of the required power is owned, the divided power after the most recent period is transmitted using virtual power and its power transmission deadline. Can be made. In addition, by using the power transmission management information, it is possible to realize alternative transmission with surplus power for virtual power and compensation of surplus power storage device 151 with actual power for virtual power by the system.
