Nonlinear Backstepping controller Design for Recovering the Available Maximum Wind Power by a Wind Energy Conversion System at its Partial Load

Abstract

This article aims to model the entities of a Wind Energy Conversion System (WECS) based on Doubly Fed Induction Generator (DFIG), to design and then to synthesize the regulators using the base technique of Backstepping. The first one will make it possible to extract the maximum of the available wind energy taking into account the variation of the air density, and the second will control the transit of the active and reactive powers exchanged with the Grid utility. We will then present the results of the simulations of the set under the Matlab-Simulink environment.
