Abstract: This paper proposes a series grid voltage compensation method able to diagnose and tolerate voltage dip faults in order to enhance the fault ride through (FRT) capability of doubly fed induction generator (DFIG)-based wind energy conversion systems. A series compensation algorithm is applied to deal with the occurrence of a voltage dip fault. Linearised mathematical models are developed for both healthy and faulty operating conditions in order to establish an appropriate and precise voltage controllers' regulation. Finally, the simulation results obtained from the studied FRT technique implementation are carried out to validate the performance of the proposed strategy.
