Abstract: This research includes study of Doubly Fed Induction Generator (DFIG) connected to variable speed Wind Energy Conversion System (WECS). WECS connected to grid is composed of back-to-back PWM converters on the rotor side. Instantaneous Reactive Power Theorem (IRPT) based control technique is used for Rotor Side Converter (RSC) control and Direct Power Control (DPC) is used for Grid Side Converter (GSC) control. Proposed control strategy is used for voltage and frequency control of DFIG. IRPT helps in reactive power compensation, attaining unity power factor and reduction of harmonics. The developed system is validated using MATLAB/Simulink for different dynamic conditions.
