Abstract

An information processing device includes: a remaining-discharge-capacity information acquiring unit configured to acquire remaining-discharge-capacity information indicating a power amount which is dischargeable by an electricity storage device connected to a plurality of customer facilities; a requested discharge power information acquiring unit configured to requested discharge power information indicating a requested power amount for discharge requested as power supply to each of the plurality of customer facilities from the electricity storage device; and a discharge amount determination unit configured to determine a storage battery discharge amount indicating an amount of power, which is discharged from the electricity storage device, based on the remaining-discharge-capacity information and the requested discharge power information.

First claim

1 . An information processing device comprising:
a remaining-discharge-capacity information acquiring unit configured to acquire remaining-discharge-capacity information indicating a power amount which is dischargeable by an electricity storage device connected to a plurality of customer facilities; a requested discharge power information acquiring unit configured to acquire requested discharge power information indicating a requested power amount for discharge requested as power supply to each of the plurality of customer facilities from the electricity storage device; and a discharge amount determination unit configured to determine a storage battery discharge amount indicating an amount of power, which is discharged from the electricity storage device, based on the remaining-discharge-capacity information and the requested discharge power information.

2 . The information processing device according to claim 1 , wherein the requested discharge power information acquiring unit acquires requested discharge power information based on load prediction information indicating a prediction value of at least one of an amount of power supplied to each of the plurality of customer facilities and an amount of power consumed by loads of each of the plurality of customer facilities.

3 . The information processing device according to claim 1 , wherein the requested discharge power information acquiring unit acquires the requested discharge power information in which a requested power amount for discharge is set every time period divided by a unit time, and
the discharge amount determination unit determines the storage battery discharge amount, which is larger than a storage battery discharge amount in a time period in which a sum of the requested power amounts for discharge of the plurality of customer facilities is relatively small, in a time period in which the sum is relatively large.

4 . The information processing device according to claim 1 , comprising:
a priority information acquiring unit configured to acquire priorities assigned to each of the plurality of customer facilities; wherein the requested discharge power information acquiring unit acquires a requested power amount for discharge every time period divided by a unit time; and the discharge amount determination unit determines a storage battery discharge amount, which is larger than a storage battery discharge amount in a time period in which a requested power amount for discharge of a customer facility with a high priority is small, in a time period in which the requested power amount for discharge of the customer facility with the high priority is large.

5 . The information processing device according to claim 4 , further comprising:
an assignment amount determination unit configured to determine an assignment power amount indicating a power amount which is virtually suppliable to the plurality of customer facilities, wherein the assignment power amount, which is larger than an assignment power amount of a customer facility with a relatively small requested power amount for discharge, is set in a customer facility with a relatively large requested power amount for discharge.

6 . The information processing device according to claim 4 , further comprising:
an assignment amount determination unit configured to determine an assignment power amount indicating a power amount which is virtually suppliable to each of the plurality of customer facilities, wherein the assignment amount determination unit determines magnitude of the assignment power amount of each of the plurality of customer facilities according to the priorities.

7 . The information processing device according to claim 5 , comprising:
a deemed amount acquiring unit configured to acquire the assignment power amount and a power supply amount supplied to each of the plurality of customer facilities; and a deemed amount determination unit configured to determine a deemed amount indicating a power amount deemed to be received from the electricity storage device by each of the plurality of customer facilities, wherein the deemed amount determination unit determines a smaller value of the assignment power amount and the power supply amount as the deemed amount.

8 . The information processing device according to claim 5 , further comprising:
a priority update information acquiring unit configured to acquire priority update information indicating power use histories of each of the plurality of customer facilities; and a priority update unit configured to, based on the priority update information, update the priorities such that the assignment power amounts of the plurality of customer facilities during a constant period become equalized or profits obtained by receiving power from the electricity storage device become equalized.

9 . The information processing device according to claim 5 , further comprising:
a power generation prediction information acquiring unit configured to acquire power generation amount prediction information indicating a prediction value of a power amount supplied by at least one of a power generator and a second electricity storage device, which are power supply sources different from a power system which supplies power to the plurality of customer facilities and the electricity storage device, wherein the discharge amount determination unit determines the storage battery discharge amount by further using the power generation amount prediction information.

10 . The information processing device according to claim 9 , wherein the requested discharge power information acquiring unit further acquires sharing possibility information indicating sharing possibility of a power amount, which is supplied from at least one of the power generator and the second electricity storage device, as the requested discharge power information, and
when the sharing possibility information indicates sharing impossibility, the assignment amount determination unit determines a power amount, which is supplied from the power generator and the second electricity storage device, as the assignment power amount of the customer facility occupying the power generator and the second electricity storage device.

11 . The information processing device according to claim 7 , further comprising:
a notification unit, wherein the notification unit compares the power supply amounts of the customer facilities with the assignment power amounts of the customer facilities, and notifies the customer facilities when a difference between the power supply amounts and the assignment power amounts exceeds a threshold value.

12 . A storage battery sharing system comprising:
an electricity storage unit configured to be connected to a plurality of customer facilities and supplying power to the customer facilities; a remaining-discharge-capacity information acquiring unit configured to acquire remaining-discharge-capacity information indicating a power amount which is dischargeable by the electricity storage unit; a requested discharge power information acquiring unit configured to acquire requested discharge power information indicating a requested power amount for discharge requested as power supply to each of the plurality of customer facilities from the electricity storage unit; a discharge amount determination unit configured to determine a storage battery discharge amount indicating power, which is discharged from the electricity storage unit, by using the remaining-discharge-capacity information and the requested discharge power information; and a controlling unit configured to control the electricity storage unit according to the storage battery discharge amount
