Abstract :
This paper deals with a voltage and frequency controller (VFC) of a stand-alone wind energy conversion system using an isolated asynchronous generator (IAG) feeding three-phase four-wire loads. The reference generator currents are estimated using the power balance theory to control the voltage and frequency of IAG system. Two-leg reduced switch integrated voltage source converter (VSC) with a battery energy storage system (BESS) is used as a VFC for the power management of the wind energy conversion system (WECS). The proposed VFC works as a voltage regulator, a load leveler, a load balancer and a harmonic eliminator in WECS. The wind power driven IAG system is modeled and simulated in the MATLAB using Simulink and sim power system (SPS) toolboxes.
