Performance and efficiency control enhancement of wind power generation system based on DFIG using three-level sparse matrix converter

Abstract Nowadays, the power generation systems based on wind turbines is increasing continuously in the world. Hence, there are intense efforts provided by researchers for the development of this area. In high power system applications, multilevel converters are a competitive alternative to the two-level inverters. In this paper, a three-level sparse matrix converter (SMC3l) associated to a grid connected variable speed wind generation (VSWG) scheme using a doubly fed induction generators (DFIGs) is investigated. Therefore, the dynamic behavior of a wind generator, including models of the wind turbine, DFIG, SMC3l control algorithm and power control is studied. Simulation results of the dynamic models of the wind generator are presented, for different operating modes sub-synchronous, synchronous and hyper-synchronous, to show the good performance and the efficiency control enhancement of the VSWG system using the proposed SMC3l.
