Performance analysis of a wind energy conversion system based on a doubly-fed induction generator

This paper is interested in the study of a wind energy conversion system (WECS) based on a doubly fed induction generator (DFIG) connected to the electric power network. The aim of this work is to compare the energy production unit performances by the use of two types of controllers. Classical PI and polynomial RST controllers are applied for the WECS control in terms of instruction tracking and robustness with respect to the wind fluctuation and the impact on the produced energy quality. A vector control with stator flux orientation of the DFIG is also presented.
