Abstract :
In this paper, a fuzzy sliding mode control algorithm is proposed to improve performances of a variable speed wind energy conversion system (WECS) connected to the grid. To reduce the converter size, a doubly fed induction generator (DFIG) is used. Using a DFIG offers also the possibility to its stator active and reactive powers to be controlled independently. The active power reference is obtained by applying the maximum power point tracking (MPPT) strategy based on speed control technique. The combination of sliding mode and fuzzy logic permits to enjoy the benefits of these two methods. The proposed approach is tested in Simulink/Matlab environment. The simulation results show good performances of the global conversion system.
