Abstract: In a power grid stabilization system, a second energy storage system has a larger energy storage capacity than a first energy storage system. A bidirectional AC/DC converter is connected between an AC power grid and a pair of input and output terminals of the first energy storage system. A first bidirectional DC/DC converter is connected between the pair of input and output terminals of the first energy storage system and a pair of input and output terminals of the second energy storage system.

Abstract: An electric power control system includes a plurality of power converters connected in parallel. Each power converter, among the plurality of power converters, converts a direct-current power of an electricity storage device connected to the power converter into an alternating-current power, and outputs the alternating-current power to the power system. The electric power control system further includes: a power generator simulation unit to simulate characteristics of the synchronous generator based on an aggregate active power to generate a phase of the alternating-current voltage; a signal generation unit to generate a control signal for the power converter, based on the phase of the alternating-current voltage. The power generator simulation unit generates a first angular frequency based on a first difference between the aggregate active power and a target value for the aggregate active power, and generates, based on the first angular frequency, the phase of the alternating-current voltage.
