    Abstract: A regulating-device-control system for controlling the operation of regulating devices for regulating the balance between electric power supply and demand includes: memory means storing, for each regulating device, correlation information expressing correlation of a state of the regulating device, an amount of power allotted to the regulating device, and an amount of variability in performance of the regulating device; determination means receiving state information that expresses the state of each regulating device and electric power information that expresses an amount of regulated power required for regulating the balance between electric power supply and demand, and, based on the correlation information, the state information, and the electric power information, determining the amount of electric power to be allotted to each regulating device such that the total value of the amount of variability in performance of each of the regulating devices is minimized under conditions in which the state of each regulating device is the state expressed by the state information and the total value of the amount of power to be allotted to the regulating devices is the amount of regulated power; and control means controlling the operation of each regulating device based on the determination result of the determination means.

    Abstract: Lower-level information processing device (20-1 to 20-n) obtain parameters used for estimating power consumption in accordance with the statuses of electric devices (30-1 to 30-n), estimate the power consumption of the electric devices (30-1 to 30-n) on the basis of the parameters, and transmits the estimated value of the estimated power consumption to an upper-level information processing device (10). The upper-level information processing device (10) determines an assignment of distribution of supply and demand on the basis of the power supply-demand capacity in a predetermined power network and the estimated value of the power consumption and transmits the determined assignments to the lower-level information processing devices (20-1 to 20-n). The lower-level information processing devices (20-1 to 20-n) controls the operations of the electric device (30-1 to 0-n) on the basis of the assignment of distribution of supply and demand.
