Power Control of Wind Turbine System based on DFIG-Generator, using Sliding Mode Technique

This paper presents the study and the modeling of a new nonlinear control technique called sliding mode control applied to the variable speed wind system based on the doubly Fed Induction generator in order to improve the performance of the wind system. The objective of this modeling is to apply the sliding mode control technique, known for its insensitivity to variations in internal and external parameters, stability, simplicity and very low response times, to control the active and reactive power Generated by the doubly Fed Induction generator. The Maximum Power Point Tracking strategy is applied to extract the maximum of the maximum power produced by the generator. The simulation results show that the wind turbine can operate at its optimum energy for a wide range of the wind speed.
