SM-MPPT Controller of DFIG Based on Variable Speed Wind Energy Conversion System

This paper deals with the modeling and control of the wind turbine based on doubly fed induction generator (dfig) via maximum power point tracking (MPPT) strategy to extract the maximum mechanical energy from the wind. In this work, the method of MPPT is elaborated and compared without wind speed measurement and with the speed of wind measurement by using tow deferents controllers PI and sliding mode. Simulations are carried out the comparison between MPPT sliding mode controller and MPPT PI controller and without wind speed measurement method, results simulation are shown that the control performance of MPPT sliding mode is superior.
