In this paper, an autonomous wind energy conversion system (WECS) is proposed using a permanent magnet synchronous generator (PMSG). The voltage and frequency (VF) of the stand alone WECS is controlled using a voltage source converter (VSC) with a battery energy storage system (BESS) at its dc link. A Scott-connected transformer is proposed for the neutral current compensation of the three-phase four-wire...
This paper deals with a solid state voltage and frequency controller for an isolated wind energy conversion system (WECS) based on capacitor excited asynchronous generator (CEAG) and feeding an induction motor load. The proposed voltage and frequency controller consists of an IGBT (insulated gate bipolar junction transistor) based voltage source converter along-with battery energy storage system (BESS)...
