This paper demonstrate the fiability and the efficiency of a proposed control law based on a combination of a sliding mode current controllers and a single input fuzzy logic controller, used to command a static synchronous compensator in order to improve voltage profile and stability of an asynchronous wind turbine despite wind speed and load variation. All simulation results as well as the modeling of the wind power system and the design of the proper controllers are described in detail in this document. NOMENCLATURE Air density. R Blades length.
