Recently various FACTS devices have been used for flexible power flow control, secure loading and damping of power
system oscillation. Some of those are used also to improve transient and dynamic stability of wind power generation system (WPGS). It
is proposed the STATCOM based on the voltage source converter (VSC) PWM technique to stabilize grid connected squirrel cage wind
generator system. The study deals with the fuzzy logic based control of wind turbine driven by squirrel cage induction generator (SCIG)
connected to grid. The proposed fuzzy logic controller (FLC) is used with nine rules to implement the control strategy for the induction
generator. These state variables used for fuzzy logic controller design are the error signals from the model of the induction machine. The
computer simulation results show the controller is satisfactory in operation of induction generator (IG) with the significant optimization
in the reactive power output. In this work the static reactive compensator (STATCOM) based on voltage source converter (VSC) PWM
Technique is presented to stabilize gird connected squirrel cage wind generator system. Simulation results clearly indicate that
STATCOM equipped with the proposed fuzzy control gives better and faster performance than STATCOM with conventional controller.

In the above work for the wind power plant application the
considered model has been simulated for STATCOM with
PI & STATCOM with fuzzy controller both under steady
state & various transient condition. The simulation results
are tabulated in the Table 3. It can be concluded that the
settling time & overshoot in Mvar generated at
STATCOM is less in case of Fuzzy compared to PI
controller. Even for the same active power generation the
reactive power generation is optimized in case of fuzzy
controlled based STATCOM as compared to PI based
STATCOM. So it is recommended to connect the
STATCOM with fuzzy controller for wind power plants
having Induction generators. STATCOM for sure gives
faster response, enhance stability & improve performance
of grid interconnected Induction generator based wind
system. Places where the switching capacitor banks are
already installed. STATCOM can be installed. The
reactive power compensation can be provided partially
