Modeling, and Dynamic control of DFIG with Integrated Battery Energy Storage System through LVRT Behavior

The Doubly Fed Induction Generator (DFIG) based wind turbine with variable-speed variable-pitch control scheme is the most popular wind power generator in the wind power industry. This machine can be operated either in grid connected or standalone mode. A thorough understanding of the modeling, control, and dynamic as well as the steady state analysis of this machine in both operation modes is necessary to optimally extract the power from the wind and accurately predict its performance. Which include Low Voltage Ride Through (LVRT) with Enhanced Flux Oriented Control (EFOC) in Rotor Side Converter (RSC) and enhance its dynamic behavior with integrated Battery Energy Storage System (BESS) at dc link capacitor. The theme of the paper is to improve the dynamic characteristics of the system
