Abstract

Modeling, control, and simulation of a wind energy conversion system equipped with a doubly fed induction generator are presented in this study. A fractional-order proportional-integral super twisting sliding mode controller (FOPI-STSMC) is used to ensure maximum power point tracking and control the stator active and reactive powers injected into the grid. A comparison of the simulation results provided by the FOPI-STSMC controller and conventional sliding mode controller is performed using MATLAB/Simulink software. The proposed FOPI-STSMC controller significantly reduced chattering while ensuring satisfactory robustness against parametric variations.
