Abstract: The use of wind energy has become an important part of world sustainable energy development. Wind energy systems are being studied much because of its great benefits as itís an environment friendly and a sustainable source of energy. Due to itís this erratic nature, power maximization concepts are necessary for extraction as much power as possible from the wind energy systems. In this paper some algorithms have been discussed to preserve the system at its highest possible plenty at all times and PID controller and Fuzzy Logic is applied. The algorithms have been used to obtain the operating points for transfer of maximum power. As such, so many maximum power point tracking techniques have been implemented and developed. These algorithms are studied and analysed, a comparative analysis and improvement is performed between PID MPPT and Fuzzy based MPPT.
