Power Control of a Wind Energy Conversion System based on a Doubly Fed Induction Generator using RST and Sliding Mode Controllers

In this paper, a power control study analysis of a wind energy conversion system (WECS) based on a doubly fed induction generator (DFIG) connected to the electric power grid is presented. The main objective of this work is to compare the energy production unit performances by the use of two types of controllers (namely, Polynomial RST and Sliding Mode (SM) Controllers) for the WECS control in terms of instruction tracking and robustness with respect to the wind fluctuation and the impact on the quality of the energy produced. A vector control with stator flux orientation of the DFIG is also presented to control the active and reactive powers between the stator and the network. To show the effectiveness of both control methods performances analysis of the system are analyzed and compared by simulation and results included in this paper.
