This book helps the researchers and industrialists working on a novel Doubly-Fed Induction Generator (DFIG) based Wind Energy Conversion System (WECS) which incorporates a Dynamic Voltage Restorer (DVR) and Energy Storage System (ESS). The DVR is in series with the output terminal of a Wind Turbine Generator (WTG) and parallel to the dc link of the WTG with the ESS. The control scheme of the WECS is designed to suppress wind power fluctuations and compensate for grid voltage disturbances, which in turn improves the Fault Ride Through (FRT) capability and the wind power penetration level....
