Abstract: In this study power system stability enhancement including wind farm based STATCOM controller has been presented. Three controllers have been used; the first lead-lag compensator, the second Proportional-Integral-Derivative (PID) and the third fuzzy logic controller were designed and simulated in this study for controlling a STATCOM at steady of transient analysis. Modeling of different part has been presented in details. The proposed controllers have been validated using a Synchronous Generator (SG) based One-Machine Infinite-Bus (OMIB) system with an integrated Wind Farm (WF) and a STATCOM. Simulation results and comparative study have been carried out. Many contributions have demonstrated in which Fuzzy logic controller present the best performance compered to both other controllers.
