This research paper presents the performance evaluation of the Direct Power Control (DPC) and Direct Torque Control (DTC) and Doubly – Fed Induction Generator (DFIG) connected to the Grid Systems. Based on the designing procedure and mathematical description of DTC and DPC, the performances of DFIG in grid are analyzed using PSCAD software. In the simulation results, % pulsation of Te, PDFIG, QDFIG and % THD values of is and ir with DFIG controllers are analyzed at network disturbance. And also harmonic analysis of is and VGRID are analyzed in the interconnected grid system. With the stepped up speed, Vs is magnified from its rated value. But, controlling of RSC is achieved by rotor current in dq+ and dq- frames through e j sl & e j s. So, the pulsation of torque Te is 2.5% less than resonant controller. In the DTC control technique, during the stepped up of the wind speed, the pulsation rating of DFIG parameters are controlled by controlling of Te. But in DPC, the stator current and voltage, gird voltage and current controls the converters of DFIG.
