An Efficient Finite Control Set Model Predictive Control Scheme for a Stand-alone Wind Turbine System

Abstract

This paper presents an enhancement of a stand-alone wind turbine system utilizing finite control set model predictive control (FCS-MPC) methodology. The enhancement based on using the predictive control for both boost and inverter power circuits. The control system get two voltage references, one for regulating dc-link voltage and the other to obtain the desired output ac voltage. Accordingly, utilizing such a control scheme can make system's time response even faster specially at different wind speeds. Moreover, effectiveness of the discussed control system is verified in case of unexpected load changes. The suggested control strategy is tested and verified utilizing MATLAB/Simulink environment.
