A power demand prediction unit 11 that predicts power demand, a rebate expectation value prediction unit 12 that calculates an expected profit per unit amount of reduced power based on the occurrence probability of demand response and the rebate value of demand response; , The first cost required for power purchase, the second cost required for generating power by the generators 2-1 to 2-n and the storage batteries 3-1 to 3-m, the supply satisfying the expected profit value and the power demand The result of adding the reserve power, which is the amount of power that can be further generated by the generators 2-1 to 2-n and the storage batteries 3-1 to 3-m after generating the amount, is used as an evaluation function. The generators 2-1 to 2-n, when the power demand is satisfied and the reserve power is generated by the amount of power purchased and the generators 2-1 to 2-n and the amount of power generated by the storage batteries 3-1 to 3-m, Satisfies the constraints of storage batteries 3-1 to 3-m and the evaluation function is Comprising reserve and generators 2-1 to 2-n so as to be small, the optimal operation plan creating unit 13 to determine the operation plan of the storage battery 3-1 to 3-m, a.
