STORAGE BATTERY OPERATION PLAN CREATING DEVICE, STORAGE BATTERY OPERATION PLAN CREATING METHOD, AND PERMANENT RECORDING MEDIUM

摘要

A storage battery operation plan creation device of an embodiment includes a planner. The planner creates an operation plan of a storage battery on the basis of a graph created on the basis of both a prediction result of each of a power demand and an amount of power generated by a system which uses renewable energy and electricity rate information representing information of an electric power unit price of each time, the graph including a link representing a change of the remaining amount of the storage battery due to charging/discharging of the storage battery at each time and information of a power cost of a destination node of the link caused by the change of the remaining amount.
