Comparison of Power Control Methods of DFIG for Wind Turbines

The objective of this work is to present the advantages of the power regulation (active and reactive power) of a wind system in order to upgrade the quality of the produced energy to grid. In this vein, a variety of power control techniques which have been applied to the wind energy system based on the doubly fed induction generator are studied and developed. Those techniques consist of Backstepping control and Sliding Mode control. For this, a study of these controls will be detailed and validated in Matlab / Simulink environment with the simultaneous utilization of the “Pitch Control” and “Maximum Power Point Tracking (MPPT)” techniques. Thus, the obtained results have demonstrated the peformances of the controls applied to the wind system Equally important, they also attest that the quality of the active and reactive powers and the voltages, of the wind system is significantly improved, indeed.
