In the event of voltage sag at the nearing of a wind park, severe currents may pass through the power electronic devices of the Doubly Fed Induction Generators (DFIGs). Hence, according to the Low Voltage Ride Through (LVRT) requirements, the wind parks are allowed to disconnect from the network after a certain time. Therefore, to avoid such actions, the LVRT requirement of wind parks is considered to be enhanced in this paper. This aim is achieved by offering a novel objective function in order to find the optimum impedance of Superconducting Fault Current Limiter (SFCL). To evaluate the effectiveness of the proposed method, it is verified in MATLAB/SIMULINK and its great performance to amend the LVRT of such wind parks is corroborated by the simulation results.
