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

摘要

A storage battery operation plan creating device according to an embodiment of the present invention has a planning unit. The planning unit creates an operation plan for the storage battery on the basis of a graph that includes links representing changes in remaining capacity according to the charging and discharging of the storage battery at timings, and information on the power cost at a link destination node, such cost arising due to a change in the remaining capacity. The graph is created on the basis of the results of predicting power demand and predicting the amount of power generated by a system that uses renewable energy, and electricity rate information representing information on the power unit price at each timing.
