Abstract :
This paper presents maximum power control of doubly-fed induction generator (DFIG) based grid-connected wind energy system. The control system used a combination of MPPT method with pitch control to extract maximum power from the wind turbine. PWM hysteresis controller is used to control the back to back converter which output is connected to the utility grid through a multivariable filter. The overall wind system is theoretically analyzed and modeled in Matlab/Simulink/ SimPowerSystems environment. The grid-connected wind system´s performances are evaluated.
