In this paper, Dynamic Voltage Restorer (DVR) based series compensation of the voltage to provide Fault Ride Through (FRT) and reactive power support is discussed. The control of DVR is crucial in order to improve the FRT capability in Doubly Fed Induction Generator (DFIG) based wind turbines. This is observed in terms of voltage sag mitigation capability, active and reactive power support without tripping and fault current control. To achieve a flexible control solution for balanced and unbalanced fault conditions, a combination of Feed-forward and Feed-back control is discussed in this paper. The advantage of utilizing this combined control is verified through MATLAB/Simulink based simulation results of a 1.5 MW grid connected DFIG based wind turbine. The results show good transient and steady-state response and good reactive power support during various fault scenarios. The results are verified for the recent updated grid code standards. © 2017 The Authors. Published by Elsevier Ltd.
