Abstract

A district heat supply plant controller for efficiently and flexibly obtaining operation plans of a district heat supply plant includes a plant operation planning device responsive to a predicted thermal load value for a current day predicted by a thermal load prediction device to determine an operation plan of the district heat supply plant. The plant operation planning device has a genetic algorithm executing device applying genetic algorithms onto an individual having rows of genes representing ON/OFF states in each time unit by 1/0 for each of the heat source devices. In the plant operation planning device, a mathematical programming executing device 4 uses an operation plan obtained by the genetic algorithm executing device 3 as its initial value to determine the operation plan of the district heat supply plant 20.
