    摘要： An electric power system control system for an electric power system in which loads and voltage control devices are connected together via nodes comprises distributed controllers for issuing control commands to the voltage control devices. The distributed controller includes a measurement value data collection functional unit, a state estimation functional unit and an optimum control functional unit. The measurement value data collection functional unit collects measurement value data from sensors measuring voltage and current in its own node and other nodes. The state estimation functional unit receives the measurement values of voltage and current of the own node and the other nodes as input data, estimates voltage or current as a state quantity of each of other nodes from which the measurement value data cannot be collected, and outputs the estimate values. The optimum control functional unit receives input data such as the measurement value data, the estimate values outputted from the state estimation functional unit and a voltage target value that has been set for each node and outputs a control command based on operation amounts to be distributed to the voltage control devices of the nodes. The voltage in the electric power system is controlled by superposition of voltage control amounts by the voltage control devices.

    摘要： Provided is a technology that improves the precision of demand regulation in an electrical power system. This power demand regulation system (10) has a power demand regulation device (11) that regulates the load applied to equipment of an electrical power system (13) by a load apparatus (15) operating by means of power from the electrical power system (13), which supplies power to consumers (12). When regulating the load to the equipment, the power demand regulation device (11) selects a load apparatus (15) as the subject of a request for an alteration of operating state on the basis of by-apparatus load information, which is information of each load apparatus (15), and a regulation target value, which is the amount of load that is to be regulated, and, in the period from the start to the end of regulation, executes a plurality of times the outputting of an alteration request that requests the alteration of the operating state of the selected load apparatus (15).

    摘要： A power demand regulating apparatus is provided which can efficiently achieve the purpose of peak shift in a power system and which can reduce the total incentive which an operator of a demand regulation server distributes to consumers having cooperated with a request for regulating an amount of energy to be used. A demand regulation server (0101) is provided with a cooperation level determining function (0111) of calculating a cooperation level which is obtained by quantifying the height of a cooperation sense of a consumer with a request for regulating an amount of energy to be used. The operator of the demand regulation server observes consumers or consumer appliances responding to the request for regulating an amount of energy to be used on the basis of the magnitude of the cooperation level and transmits the request to only the consumers or the consumer appliances.
