Abstract: Doubly Fed Induction Generators have become popular among renewable energy technology associated with wind farms in distribution systems. The Grid Code requirements on LVRT capability of grid connected DFIG systems have gained attention during last few decades. Dynamic Voltage Restorer has emerged as one of the promising, reliable and stable solution for enhancing LVRT capability of grid connected wind generators in many countries. A state of the art review is presented in this paper on the various control strategies adopted in DVR connected DFIG wind farms by various researchers. A MATLAB Simulink based DFIG wind farm is analysed with symmetric and asymmetric faults and PID controller based DVR is implemented as a solution to enhance the LVRT capability of the system. The active and reactive power flow as well as voltage during fault period is restored and compensated successfully.
