Renewable energy resources are alternative approach of fossil fuel resources, which are being continuously available throughout the year. Wind is one of the major fastest growing renewable energy resource which produces large amount of energy. Although wind energy is easily available, the speed of wind is not constant throughout the time. It depends on the region. So, several techniques have been discussed to harness maximum power from wind energy. This paper presents about four types of maximum power point techniques (MPPT) like Optimal torque (OT), Tip Speed Ratio (TSR), Perturb and Observe (P&O) and Fuzzy Logic Control (FLC) used in wind energy conversion system.
