Control Strategies for DFIG based on Wind Energy Conversion System using RST and Fuzzy Logic Controllers

摘要

In this paper, control strategies of the MPPT for the extraction of the maximum power for a wind energy conversion system (WECS) based on a doubly fed induction generator(DFIG) is presented.The main objective of this work is to compare the energy production unit performances of WECS based on DFIG connected to the electric power grid by the use of the RST and Fuzzy Logic Controllers.In this work, an appropriate model for WECS and vector control strategy for DFIG are established. A comparative study was made between the RST and the Fuzzy Logic controller.The performances of the proposed controllers in terms of set point tracking, speed response, and robustness with respect to sudden variations in the DFIG parameters is demonstrated through an illustrative simulation in Matlab/Simulink.
