Performance Enhancement of Wind Turbine Connected To 2 L-VSI Grid-Side and Passive Generator Side Converters Based on MPC

Abstract

Harmonic distortion management and power quality requirements are becoming more and more important for wind energy generation systems. Additionally, with the development of power electronics, variable speed has grown quickly in recent years. Electrical generators, machine-side converters, and grid-side converters are the three essential components of a Wind Power Conversion System (WECS). Noted that, because of its unique properties, the permanent magnet synchronous generator is one of the most popular options among electrical generators. Grid-side converters and synchronous generators are both used to inject electrical power into the utility grid once the wind energy has been converted to the appropriate electrical power. Hence, to select the most appropriate topology and control strategy for the machine-side converter, an analysis of several topologies and control methods is necessary. This study focuses on Model Predictive Control (MPC) application for a surface mount permanent magnet synchronous machine wind turbine. The model used is the electrical model for the machine. Considering the complicated and highly nonlinear aerodynamic system of the wind turbines is chosen on the power converters. MPC is a relatively new application in power electronics yet a promising control method. Furthermore, a simplified model of the turbine is provided and the MPC code is generated in MATLAB and Simulink.
