ABSTRACT: The objective of this article is the study of the dynamic behavior of a wind turbine based on doubly fed induction generator (DFIG) with Maximum Power Point Tracking (MPPT) without enslavement of speed and PITCH control. The DFIG stator is directly connected to the grid however; the rotor is linked via a power electronic converter (rectifier, filter, and inverter). The stator active and reactive powers are controlled directly by adjusting the DFIG rotor quantities, while applying direct vector control based on a first order sliding mode controller (SMC).

KEYWORDS: Wind turbine, MPPT, PITCH, DFIG, active and reactive power, sliding mode
