Abstract
This report presents the proposal of finite control set model predictive control (FCS-MPC) for the control of the inverter switching signals of a grid tied wind turbine back-to-back converter. Primary control objectives are tracking of DC-link voltage, and power references, in the context of grid following. The controllers ability to reduce inverter switching loses is also considered. Performance is compared to a PI controller representing the industry standard. To facilitate predictive control, a model of the converter and filter dynamics is derived, and presented in state space form. Simulation of converter, filter and grid is performed. Results does not shown meaningful performance advantages to suggest the proposed method as a viable alternative to industry standard PI control. However, the prospect of further development and improvements discussed suggest its potential.
