A Voltage Control Method in Coordination with an SVR using Distributed Energy Resources in Customers for System Voltage Stabilization

Abstract

According to the increase of the amount of renewable energy, voltage control of the distribution system is becoming more important. Thus we propose a voltage control method of power conditioning systems (PCSs) in the customers serving as virtual power plant (VPP) with the step voltage regulator (SVR). The proposed method is verified by the simulation and experimental results. As a result, it is clarified that PCSs are able to control voltage moderately and cooperate with SVR under several voltage fluctuation conditions.
