Comparative Study Between Direct Vector Control and Fuzzy Sliding Mode Controller in Three-Level Space Vector Modulation Inverter of Reactive and Active Power Command of DFIG-Based Wind Turbine Systems

Abstract

This article deals with the dynamic simulation of a directly driven wind turbine (WT) with a full-scale converter as the interface to the grid. Using the doubly fed induction Generator (DFIG), the system is controlled by two command strategies. I the first step, we have considered the direct vector control (DVC) strategy with three-level space vector modulation (SVM) and in the second one, we have applied the fuzzy sliding mode control (FSMC) strategy with three-level SVM inverter. Simulation results investigated good performances of both proposed non-linear approaches.
