A fuzzy controller for improving Fault Ride-Through (FRT) capability of Variable Speed Wind Turbines (WTs) equipped with\r\nDoubly Fed Induction Generator (DFIG) is presented. The controller is designed in order to compensate the voltage at the Point of\r\nCommon Coupling (PCC) by regulating the reactive and active power generated by WTs. The performances of the controller are\r\nevaluated in some case studies considering a different number of wind farms in different locations. Simulations, carried out on a\r\nreal 37-bus Italian weak distribution system, confirmed that the proposed controller can enhance the FRT capability in many cases.
