Abstract

This research work presents a model predictive current (MPC) controller for doubly fed induction generators (DFIG) and wind energy conversion systems (WECS) by employing a 5-level cascade H-bridge (CHB), an inverter-based machine side converter (MSC), and a grid side converter (GSC). The proposed MPC system is used to effectively control MSC and GSC operation under unbalanced grid voltage conditions. Here, 5-level CHB is employed in MSC and GSC to reduce harmonics and improve both converters' performance. In this paper, the proposed MPC is implemented and compared with the conventional PI controller. Under unbalanced grid voltage conditions, the obtained proposed MPC results outperform a conventional PI controller. The entire proposed MPC controller for DFIG-WECS employing 5-Level CHB is implemented and tested using MATLAB/SIMULINK 2018a software.
