WIND POWER GENERATION SYSTEM WITH POWER STORAGE DEVICE

A wind power generation system with a power storage device includes a wind power generation system, a power storage device system, and a reactive power controller. The wind power generation system includes a wind power generator, a first power conversion circuit, a first control circuit, a first filter capacitor, and a circuit breaker interposed between the first filter capacitor and a grid connection point. The wind power generation system is configured to output the electric power converted by the first power conversion circuit to an electric power grid via the grid connection point. The power storage device system includes a power storage device, a second power conversion circuit, and a second control circuit that controls the second power conversion circuit to perform load leveling operation. The reactive power controller causes the second power conversion circuit to perform reactive power compensation operation.
