Abstract


The purpose of this work is to design and to discuss various strategies of maximum power point tracking (MPPT) control schemes and pitch angle control methodologies for wind energy conversion systems (WECS) based on Doubly Fed Induction Generator (DFIG). The proposed controls allow the generator to monitor the optimal operating points of the turbines regardless of wind speed variations, system parameters disturbance, and parameters variation. Simulation of WECS based on a 1.5MW wound rotor induction generator under MATLAB/SIMULINK is carried out using the PI-controller (PIC), RST controller and Fuzzy Logic Controller (FLC). Analysis and comparisons are made for different operating scenarios: Reference tracking, robustness under variable wind speed conditions and parameters variation. The application of FLC provides a very interesting outcome to the robustness and the dynamic challenges.
