Voltage Control Method of Isolated Wind Power System

Abstract

This paper deals with the voltage controller of an isolated wind power system consisting of asynchronous generator driven by wind turbine. The proposed voltage controller consists of IGBT switch-based voltage source converter along with battery energy storage system at its DC link. The proposed controller controls the system voltage with variation of consumer lagging loads with the bidirectional active and reactive power flow capability. The proposed electro-mechanical system along with its controller is modeled and simulated in MATLAB using Simulink and SimPowerSytem block-set. Performance of the proposed controller is demonstrated by taking different electrical load for the voltage control of a wind generator system driven by wind turbine.
