Modelling and simulation of a wind system using variable wind regimes with Backstepping control of DFIG

Abstract

Nowadays wind turbine power is considered as the most reliable solution for power generation to complement the other power sources. While the majority of the established wind turbines have a constant speed, the use of wind turbines equipped with a variable speed is increasing. The Asynchronous Generator is a machine that has shown a great performance and it is currently used in the wind turbine industry. In the present study we propose a model of wind system with doubly Fed Induction Generator using variable wind regimes modelling. We use Matlab / Simulink software to analyse the performance of this system.
