“…Indeed, this wind system type, using DFIG generator and two converters in back-to-back mode that connects the rotor of generator with grid, has many advantages. For example, the power converters employed are dimensioned to pass just a fraction of the total generated power and consequently, this characteristic allows reducing losses in the power electronics components, maximizing power capture, smoothing the power transmission and less mechanical stresses [5]. On the other hand, by dint of the high variability nature of wind speed, DFIG-based variable speed WGS are a very efficient way for wind energy gathering [4], because this provides better flexibility in power conversion and also more stability in voltage and frequency control in the power systems to which these generators are connected [6].…”

This paper appraises the performances of two control scenarios, for doubly fed induction generator (DFIG) operating in wind generation system (WGS), which are the direct decoupled control (DDC) and indirect decoupled control (IDC). Both control scenarios studied combines vector control and Maximum Power Point Tracking (MPPT) control theory so as to maximize the captured power through wind turbine. Modeling of DFIG based WGS and details of both control scenarios have been presented, a proportional integral controller is employed in the active and reactive power control loops for both control methods. The performance of the both control scenarios in terms of power reference tracking and robustness against machine parameters inconstancy has been shown, analyzed and compared, which can afford a reference to the operators and engineers of a wind farm. All simulations have been implemented via MATLAB/Simulink.
