A New Adaptive Neuro-Fuzzy Inference System (ANFIS) and PI Controller to Voltage Regulation of Power System Equipped by Wind Turbine

In this paper, new Adaptive Neuro-Fuzzy Inference System (ANFIS) and PI controller have
been proposed and investigated which the power system is equipped by Static Var
Compensator (SVC) and small wind turbine. The SVC is controlled by PI controller optimized
by genetic algorithm (GA) to regulate the voltage profile. To demonstrate the efficiency of
proposed controller, a Single Machine Infinite Bus (SMIB) has been considered, in which
small fluctuation of mechanical damped has been applied to improve the transient stability and
has been evaluated using a relative rotor criteria. Obtained results have demonstrated a better
performance with ANFIS and PI controller in which both voltage and transient stability have
been controlled perfectly.
