Abstract:
An electric power grid control system is provided with: distributed generators connected to an electric power grid; and voltage measurement units that measure voltage at connection points of the distributed generators to the electric power grid. When voltage at a connection point to the electric power grid deviates from a predetermined acceptable range, a centralized control device equally allocates a voltage adjustment amount for returning the voltage to the acceptable range to all distributed generators belonging to a predetermined group that was set in advance. Distribution processing devices cause the distributed generators to adjust voltage at the connection points in accordance with the voltage adjustment amount allocated from the centralized control device.
