DEMAND-SUPPLY PLANNING DEVICE, DEMAND-SUPPLY PLANNING METHOD, DEMAND-SUPPLY PLANNING PROGRAM, AND RECORDING MEDIUM

摘要

A demand-supply planning device includes: a power demand predicting unit that predicts power demand; an expected rebate value predicting unit that calculates an expected profit value per unit amount of reduced power based on an occurrence probability of a demand response and a rebate value to be acquired through the demand response; and an optimal operation plan creating unit that sets an addition result of a first cost for power purchase, a second cost for power generation in power generators and storage batteries, and a multiplication result of the expected profit value and reserve power, which is an amount of power capable of being further generated by the power generators and the storage batteries after an amount of power supplied satisfying the power demand is generated, as an evaluation function and determines an operation plan of the reserve power and the power generators and the storage batteries.

1. A demand-supply planning device comprising:
a power demand predicting unit that performs prediction of power demand; an expected profit value predicting unit to calculate an expected profit value per unit amount of reduced power based on an occurrence probability of a demand response and a rebate value to be acquired through the demand response; and an optimal operation plan creating unit to set a result of subtracting a multiplication result of the expected profit value and reserve power, which is an amount of power capable of being further generated by the power supply facility after an amount of power supplied satisfying the power demand is generated from an addition result of a first cost for power purchase, a second cost for power generation by a power supply facility, as an evaluation function, and to determine the reserve power and an operation plan of the power supply facility so as to satisfy the power demand with an amount of power purchased and the amount of power generated by the power supply facility, to satisfy a constraint condition of the power supply facility when the reserve power is generated, and to minimize the evaluation function.
