ABSTRACT
A new sensor-less method for maximum power point tracking (MPPT) is introduced for a system of wind power generation. This method is based upon a modified variable step hill climb search (HCS) technique, with some modifications being made, on the basis of a simple and novel idea. The step sizes of the hill climbing technique is determined totally independent of the wind velocity and the rotor speed, without the need for any prior information of the wind power conversion system's (WECS) characteristics and configurations. Therefore it is suitable for different kinds of wind power systems.The new techniques were used in this study, show very fast performance, and also can sense the wind speed changes accurately as well as maintaining its performance under wind disturbances. Simulations are used to investigate the new method and the results support the feasibility of the presented MPPT method
