Facility planning device for heat and power facilities, and facility planning method for heat and power facilities

The purpose of the present invention is to create a facility plan for heat and power facilities forming an energy network, wherein the arrangement and location of the heat and power facilities are also determined by taking into account the power required to circulate the heating medium. The present invention is characterized by being provided with: a heat and power demand prediction unit which calculates a plurality of predicted values of the heat and power demands by consumers and probabilities of the plurality of predicted values of the heat and power demands, on the basis of consumer information; a facility configuration/arrangement plan calculation unit which generates groups of facility configuration/arrangement plans by using the plurality of predicted values of the heat and power demands, heat and power facility group information, which groups together heat and power facilities serving as candidates to be arranged, arrangement candidate setting information relating to the arrangement of the heat and power facilities, and circulation power information indicating information relating to both the pressure loss of the heat supply piping and the pumping power required to accommodate the pressure loss and thereby circulate the heating medium; and an expected cost value evaluation unit which determines a final facility configuration/arrangement plan by using both the groups of facility configuration/arrangement plans, which are generated based on the plurality of predicted values of the heat and power demands, and the probabilities of the plurality of predicted values of the heat and power demands. Thus, the present invention makes it possible to create a facility plan for heat and power facilities forming an energy network, wherein the arrangement and location of heat source facilities are also optimized at the same time by taking into account the power required to circulate the heating medium.
