Abstract To study voltage support function of energy storage system, the feasibility of solving voltage fluctuation problem induced by solar power generation system by energy storage system has been analyzed. In order to solve the problem of voltage fluctuation in electric power network induced by quick change of active power from solar power generation system, scheme of compensating the quick changing active power by battery energy storage system is designed, regulating voltage of electric power network. Voltage support function of energy storage system for electric power network with different ratios of inductance and resistance in three cases has been simulated. Simulation results show that fluctuation of voltage induced by solar power generation system in electric power network with lower ratio of inductance and resistance can be solved more effectively by active power compensation with battery energy storage system.
