The energy renewal highlights wind energy system the prominent ways to turn down the environment pollution. The integration and penetration of these energy sources in power system have tended to be a dare for network managers, mainly, with wind turbines that do not tighten control of reactive power. In this paper, a fuzzy logic based supplementary controller for static var compensator (SVC) is evolved which is utilized for decreasing the rotor angle oscillations and to patch up the transient stability of the power system involving a distributed wind generation. Generator speed and the electrical power are selected as input signals for the fuzzy logic controller (FLC). Several fault disturbance simulation results are treated to emphasize the effective upshot of the suggested controller in a multi-machine (IEEE 30-bus) power system.
