This paper describes the control scheme to extract the maximum power from PMSG based wind energy conversion system (WECS) using Maximum Power Point Tracking Algorithm (MPPT) in which inverter and rectifiers are used to handle wide range of wind speeds. In the wind system the PMSG is used. Because Permanent magnet synchronous generators(PMSGs) have high efficiency and high reliability compared with induction generators. this is because not required and there are no copper losses in the rotor circuits. moreover, because of the smaller size of the PMSG, the weight of the wind turbine is reduced. Among various PMSGs, interior PMSGs are especially advantageous from the standpoints of efficiency and power generation owing to the reluctance torque. An improved active power control method for variable speed wind turbine to enhance the inertial response and damping capability during transient events, by using the optimized power point tracking (OPPT) inertia control (VIC) curves according to the frequency deviation, is proposed to release the “hidden” kinetic energy and provide controller, which shifts the turbine operating point from the maximum power point tracking (MPPT) curve to the virtual dynamic frequency support to the grid. The effects of the VIC on power oscillation damping capability are theoretically evaluated. Thus, inertial response and power oscillation damping function can be obtained in a single controller by the proposed OPPT control. The model of wind conversion system is built and simulated along with PI controller and fuzzy controller to reduce oscillations and increase the active power by using MATLAB/SIMULINK software will be developed.
