Abstract This paper deals with a small wind energy conversion system (WECS), equipped with a variable-speed wind turbine and a fuzzy Takagi-Sugeno-Kang (TSK) wind estimator is proposed for the maximum power extraction. Using the estimated wind speed, which is usually obtained employing anemometers, a fuzzy-based control system is able to determine and regulate rotor speed for the maximum power extraction. The adoption of a sensorless strategy, especially for small size wind generation systems, leads to lower costs and improved reliability of the overall system.

This paper presents on overview of maximum power point tracking (MPPT) techniques for different types of wind energy conversion systems (WECS). In order to obtain maximum power from the wind turbine (WT), variable speed wind energy conversion systems (VSWECSs) are preferred over constant speed wind energy conversion systems (CSWECSs).In VSWECS, the rotational speed of the turbine is varied by controlling the aerodynamic or electrical parameters of WECS to maintain a constant tip-speed ratio (TSR). This is called maximum power point tracking and different techniques are applied to WECS namely Squirrel Cage Induction Generators (SCIGs) based WECS, Permanent Magnet Synchronous Generators (PMSGs) based WECS.
