| 简介 |
A voltage reactive power control device and a voltage reactive power control program that can suppress a bus voltage fluctuation of a power distribution transformer station due to an output fluctuation of a renewable energy power generation by a simple control that utilizes a battery, and can achieve a cooperative action with already-existing facilities. This device includes a bus voltage fluctuation extracting unit that extracts the bus voltage fluctuation from the voltage of a secondary-side bus, an RE component extracting unit that extracts the fluctuation component due to the 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 the 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. |
