Patent ID: 8768527

Claim:
A power demand/supply management server which is connected to a plurality of power operating devices that control electrical equipment through a communication network and which distributes control information defining control contents for the electrical equipment to the power operating device, the power demand/supply management server comprising: a memory unit that stores a predetermined energy consumption model for predicting an electricity daily load curve indicating an electrical power consumption per predetermined time using parameters which are control-target equipment information of the power managing device, applied-rate-plan group information indicating an electricity unit meter-charge applied to the power operating device and an applied period of the electricity unit meter-charge, and control contents to the electrical equipment and a weather condition; information obtaining unit that obtains control preference information including cost evaluation values which are barometers indicating a compatibility of restraint conditions to a comfort and an electricity bill for each consumer, the comfort and the electricity bill being set and input by the power operating device; a control simulating unit which obtains the energy consumption model from the memory unit in order to calculate the electricity daily load curve, and which simulates a total cost evaluation value that is a total of the cost evaluation values for the comfort and the electricity bill for a predetermined period using the calculated electricity daily load curve, the applied-rate-plan group information stored in the memory unit and the obtained control preference information; an individual-consumer control optimizing unit which obtains the control-target equipment information from the memory unit, generates a plurality of candidate data having the control contents to the electrical equipment changed and set, instructs the control simulating unit to perform simulation on the plurality of generated candidate data, selects the control contents to the electrical equipment so that the total cost evaluation value becomes minimum among the plurality of candidate data as a result of the simulation, and generates the electrical equipment control information based on the selected control contents; and a transmitting unit that transmits the generated electrical equipment control information to the power operating device.
