Abstract

Abstract : This study deals with the operation and control of a doubly fed induction generator (DFIG)‐based off‐grid wind energy conversion system (WECS). Two back‐to‐back connected voltage source converters with intermediate DC‐link supported with a battery energy storage system are used as a voltage and frequency controller (VFC). A field oriented control algorithm is used for VFC to perform as a load leveller, a load balancer, an active filter along with a VFC. Simulation results are verified on a developed prototype of VFC for DFIG‐based off‐grid WECS. The performance of WECS is demonstrated feeding non‐linear and dynamic loads.
