Storage battery management device, storage battery, method of managing storage battery, and storage medium
First Claim
1. A storage battery management device for managing a storage battery, comprising:
- a memory storing a set of instructions; and
a processor configured to execute the set of instructions to;
determine an upper limit of an amount of power discharged from the storage battery for each of discharging time periods divided for each unit time, based on;
remaining discharge capacity information indicating an amount of power that can be supplied to a load from the storage battery, andpower purchasing price information indicating a power purchasing price for each discharging time period,wherein the upper limit is determined so that an upper limit in a discharging time period having a relatively high power purchasing price is larger than an upper limit in a discharging time period having a relatively low power purchasing price.

Abstract
Provided is a storage battery management device (10) including a price information acquisition unit (11) that acquires power purchasing price information indicating a power purchasing price for each time period of power supplied from an electric power system, a remaining discharge capacity information acquisition unit (12) that acquires remaining discharge capacity information indicating the amount of power that can be discharged to a load from a storage battery, and a discharging schedule generation unit (13) that generates a discharging schedule in which an upper limit of the amount of power discharged from the storage battery is determined for each of a plurality of discharging time periods divided for each unit time, using the power purchasing price information and the remaining discharge capacity information.

12. A storage battery management device for managing a storage battery, comprising:
-
a memory storing a set of instructions; and a processor configured to execute the set of instructions to; determine an upper limit of an amount of power discharged from the storage battery for each of discharging time periods divided for each unit time, on the basis of; remaining discharge capacity information indicating an amount of power that can be supplied to a load from the storage battery, and power purchasing price information indicating a power purchasing price for each discharging time period, wherein a plurality of the discharging time periods are divided into a first group in which discharging time periods having a relatively high power purchasing price are collected and a second group in which discharging time periods having a relatively low power purchasing price are collected, wherein a maximum amount of power that can be discharged in each discharging time period is specified on the basis of the upper limit of the amount of power, and wherein a discharging schedule is generated so that a sum of a first total which is a total of maximum amounts of power in respective discharging time periods included in the first group and a second total which is a total of maximum amounts of power in respective discharging time periods included in the second group, which are temporally prior to at least one discharging time period included in the first group, does not exceed a predetermined amount of power which is determined on the basis of the remaining discharge capacity information. - View Dependent Claims (16)

13. A storage battery management device for managing a storage battery, comprising:
-
a memory storing a set of instructions; and a processor configured to execute the set of instructions to; determine an upper limit of an amount of power discharged from the storage battery for each of discharging time periods divided for each unit time, on the basis of; remaining discharge capacity information indicating an amount of power that can be supplied to a load from the storage battery, power purchasing price information indicating a power purchasing price for each discharging time period, predicted power generation information indicating a predicted power generation amount for each discharging time period of a power generation device that supplies power to the load or the storage battery, and power selling price information indicating a selling price of power which is generated by the power generation device, wherein the upper limit is determined on a premise that power generated by the power generation device is supplied to the load or the storage battery in a time period having a selling price of power equal to or lower than the power purchasing price and the power generated by the power generation device is not supplied to the load or the storage battery in a time period having a selling price of power higher than the power purchasing price.

14. A storage battery management device for managing a storage battery, comprising:
-
a memory storing a set of instructions; and a processor configured to execute the set of instructions to; determine an upper limit of an amount of power discharged from the storage battery for each of discharging time periods divided for each unit time, on the basis of; remaining discharge capacity information indicating an amount of power that can be supplied to a load from the storage battery, and privilege information indicating a privilege for each discharging time period according to an amount of power supplied from an electric power system, wherein the privilege information is information indicating that a predetermined privilege is obtained when an amount of power supplied from the electric power system in a first time period is smaller than a predetermined value, and wherein an upper limit which is larger than upper limits for the other discharging time periods is determined for a discharging time period included in the first time period.

15. A storage battery management device for managing a storage battery, comprising:
-
a memory storing a set of instructions; and a processor configured to execute the set of instructions to; determine an upper limit of an amount of power discharged from the storage battery for each of discharging time periods divided for each unit time, on the basis of remaining discharge capacity information indicating an amount of power that can be supplied to a load from the storage battery, wherein a maximum amount of power that can be discharged in each discharging time period which is determined on the basis of the upper limit, is an amount of power which is obtained by subtracting a predetermined amount from an amount of power that can be supplied to the load from the storage battery.
