Abstract: 

This paper proposes a new direct power control (DPC) for wind turbine system driven by doubly fed induction generator (DFIG) in order to track maximum absorbable power in different wind speeds. New DPC employs input- output linearization and sliding mode nonlinear controller for robust control of active and reactive power to obtain maximum power from wind turbine. As the three phases voltages with desired frequency is injected to rotor windings using space vector modulation with constant switching frequency. The conventional look up table method and a new online method for determining maximum absorbable power has been used every instant. Simulation results on 660 kw wind turbine show that the proposed algorithm has low error for tracking maximum power in compression with the existing method during machine parameters variation.
