  • Patent number: 8768527
    Abstract: A power demand/supply management server (10) obtains information defining restraint contents to a comfort and an electricity bill from a consumer power operating device (2). An individual-consumer control optimizing unit of the power demand/supply management server (10) calculates control contents to an electrical equipment having a minimum cost evaluation value based on a simulation result of cost evaluation values which are barometers for evaluating a comfort and an electricity bill excessiveness, and transmits the calculated control contents to the consumer power operating device (2). Also, a whole-consumer optimizing unit of the power demand/supply management server (10) calculates the most appropriate electricity unit meter-charge that ensures a necessary demand suppression plan level throughout the whole power system based on an electricity daily load curve for each consumer.

  • Patent number: 8396601
    Abstract: A customer-dedicated energy management apparatus includes an air-conditioner partial-road characteristics identification unit for creating air-conditioning partial-road characteristics by using air-conditioning operation achievement data in the past, an intra-room heat-capacity characteristics identification unit for creating intra-room heat-capacity characteristics by using the air-conditioning operation achievement data in the past, and intra-room state value data, an air-conditioning setting temperature calculation unit for determining an air-conditioning setting temperature by using the air-conditioning partial-road characteristics and the intra-room heat-capacity characteristics, the setting temperature being appropriate for implementing an air-conditioning power-consumption-amount suppression target value determined, and an air-conditioner control unit for controlling an air conditioner so that the setting temperature determined will be implemented.
