In this paper, we are going to introduce the modeling and control of the DFIG (Doubly-Fed Induction Generator) used in the WECS (Wind Energy Conversion System). A Non-Linear control based on the backstepping approach to control the RSC (Rotor Side Converter) is proposed in this study. The aim is to maximize the power extracted from WT (Wind Turbine). This is accomplished, specifically, by controlling both the active and reactive power of the DFIG. To validate and simulate the effectiveness of this control strategy, Matlab/Simulink software environment was used. The obtained results are analyzed and discussed to evaluate the system performances in terms of robustness against random wind speed variations and parametric variations as well. The proposed simulations show that this technique presents high performances compared to other classical linear controllers. |
