Abstract
A voltage reactive power control device includes a bus voltage fluctuation extracting unit that extracts a bus voltage fluctuation from a voltage of a secondary-side bus, an RE component extracting unit that extracts a fluctuation component due to renewable energy power generation from the bus voltage fluctuation, a creating unit that creates a reactive power command value for suppressing the fluctuation component based on the bus voltage fluctuation component due to the renewable energy power generation extracted by the RE component extracting unit, and a control unit that executes the reactive power control on a battery system based on the reactive power command value. The RE component extracting unit extracts the fluctuation component due to the renewable energy power generation by eliminating the fluctuation components other than the fluctuation component due to the renewable energy power generation from the bus voltage fluctuation.
