In this paper deals with an improved active power control method for variable speed wind turbine to enhance the inertial response with fuzzy control and damping capability during transient events are analysed in this paper. According to the frequency deviation the optimized power point tracking (OPPT) controller, which shifts the turbine operating point from the maximum power point tracking (MPPT) curve to the virtual inertia control (VIC) curves, is proposed to release the “hidden” kinetic energy and provide dynamic frequency support to the grid. Compared to the conventional supplementary derivative regulator-based inertia control, the proposed control scheme can not only provide fast inertial response, but also increase the system damping capability during transient events. Thus, inertial response and power oscillation damping function can be obtained in a single controller by the proposed OPPT control. Here we are using the fuzzy controller compared to other controllers i.e. The fuzzy controller is the most suitable for the human decision-making mechanism, providing the operation of an electronic system with decisions of experts. In addition, using the fuzzy controller for a nonlinear system allows for a reduction of uncertain effects in the system control and improves the efficiency. By using the simulation results we can analyze the proposed control strategy on providing rapid inertial response and enhanced system damping.
