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.
