Cogeneration system, operation plan creation method and operation plan creation apparatus

摘要

PPROBLEM TO BE SOLVED: To make a suitable operation plan with small amounts of calculation. PSOLUTION: The operation plan creation device of a cogeneration system equipped with a power generation device and a heat accumulation device for accumulating heat by collecting an exhaust heat is provided with: a prediction amount storage part 51 for storing future power usage prediction value and a future heat usage prediction value; an adaptivity calculation part 52 for determining the amounts of energy reduction in the case of operating a power generation device on the basis of the power usage prediction value and the heat usage prediction value so that it can be represented with an individual consisting of gene indicating the amounts of power generation by time period; an individual group generation part 53 for generating a first generation being the group of individuals; a load follow-up individual generation part 54 for generating a load follow-up individual whose gene is at least partially associated with the power usage predication value; a mating part 55 for generating the group of individuals in a new generation from the group of individuals in the previous generation by a genetic algorithm so that the amounts of energy reduction can be increased; and an operation plan creation part 56 for creating an operation plan from the individual whose amounts of energy reduction are the largest among the group of individuals in the last generation.
