A real-time Backstepping control strategy for a doubly fed induction generator based wind energy conversion system

Abstract

Nowadays, the continuously increasing of the energy consumption all over the world presents the cause of renewable energy sources development. In this context, wind energy conversion systems (WECS) based on double fed induction generator (DFIG) are widely used in both grid connected and stand-alone modes. In both cases, management and control technologies are widely developed in the literature. In this paper, in order to control and regulate stator output voltage and frequency whether for load demand power variations and wind speed fluctuations, a study of the stand-alone DFIG based WECS using Backstepping controller is made, developed and tested. Experimental results are carried out using a 1.5 Kw DFIG and a dSpace DS1104 card. Results demonstrate performances of the Backstepping control strategy.
