PROBLEM TO BE SOLVED: To suppress maximum transmitting/receiving electric power so as to control to bring the transmitting/receiving electric power of a small-scale system to/from an upper-level system close to a planned value.SOLUTION: A device 40 for creating a demand and supply plan of a storage battery executes arithmetic processing for minimizing an objective function using as variables the difference between transmitting/receiving electric power to/from an upper level system 2 and a planned value, and the square of the difference, to create operation plan information 50 of a storage battery 10, by applying as constraint conditions: a demand and supply balance using as variables an estimation value of power generated by natural energy power generation such as a photovoltaic power device 20 and a wind power generation device 21, charging/discharging electric power of the storage battery 10, an estimation value of power consumption of a load 30, and transmitting/receiving electric power to/from the upper level system 2; and upper/lower limit values of SOC (state of charge) of the battery 10.
