Voltage reactive power control device and voltage reactive power control program

摘要

Voltage reactive power control device and voltage reactive power that can control bus voltage fluctuations in distribution substations caused by fluctuations in the output of renewable energy power generation with simple control using storage batteries and can be coordinated with existing facilities Provide a control program. A bus voltage fluctuation extracting unit that extracts a bus voltage fluctuation from the voltage on the secondary side bus, an RE part extracting part that extracts a fluctuation due to renewable energy generation from the bus voltage fluctuation, and a regenerative extracted by the RE part extracting part A generating unit that generates a reactive power command value for suppressing the fluctuation based on bus voltage fluctuation due to energy generation, and a control unit that performs reactive power control of the storage battery system based on the reactive power command value. The RE component extraction unit extracts a variation due to the renewable energy power generation by removing a variation other than the variation due to the renewable energy power generation from the bus voltage variation.
