Nirmal Kumar Abstract – This paper presents Maximum Power Point Research on performance improvement of and cost Control for variable speed wind turbine driven permanent- reduction in such non–conventional energy conversion magnet generator. The wind turbine generator is operated systems is being accorded the highest priority [8].Wind such that the rotor speed varies according to wind speed to power generation has a strong connection to rotating adjust the duty cycle of power converter and maximizes Wind Energy Conversion System (WECS) efficiency. The machinery and hence its practical application is most maximum power point for each speed value is traced using promising. Wind generator control methods have already Maximum Power Point Tracking (MPPT) algorithm. The been proposed to efficiently utilize the wind power which rotating speed of permanent-magnet generator should be is prone to fluctuation every moment. The induction type adjusted in the real time to capture maximum wind power. machine has the advantages of robustness, low cost and The system includes the wind-turbine, permanent-magnet
