Modeling and Control of an Aerogenerator Utilizing DFIG and Direct Matrix Converter Technology

This paper explores the control challenges associated with wind energy conversion systems (WECS) incorporating a doubly fed induction generator (DFIG) powered by advanced converters. With the increasing prominence of power electronics, particular emphasis is placed on the utilization of a new generation of converters, specifically the AC/AC matrix converter. This converter offers direct AC/AC power conversion, bidirectional power flow, and nearly sinusoidal input and output waveforms. The study presented in this paper focuses on assessing the performance of a wind turbine equipped with a DFIG and powered by a matrix converter, which employs the maximum power point tracking technique to get the maximum power obtainable. The studied system is evaluated within the dq coordinates. The proposed control scheme is implemented, and its efficacy is assessed through simulation results using MatLab/Simulink.
