Abstract
This paper proposes an improvement of the finite control set model predictive control (FCS-MPC) strategy for enhancing the voltage regulation performance of a voltage source converter (VSC) used for standalone microgrid and uninterrupted power supply (UPS) applications. The modification is based on tracking the voltage reference trajectory derivative using a single step prediction horizon. The main results are: 1) reduction of the total harmonic distortion (THD) and better tracking of fundamental voltage component compared with the conventional FCS-MPC, 2) lower computational burden compared to multi-step prediction horizon strategies, and 3) preserved fast dynamic response to abrupt load changes. These findings have been validated for both linear and nonlinear loads through experimental verification on a 15kW two-level VSC prototype.
