Model Predictive Current Control of Dual-Mode Voltage Source Inverter Operations: Islanded and Grid-Connected

Abstract

Model predictive control (MPC) has been a research topic for power converters control due to its simplicity, easy inclusion of constraints, fast dynamic response, among others. This work proposes the use of MPC as a current regulator of a voltage source inverter (VSI) in a dual-mode operation. On one hand, the VSI is used to provide current to a load from a photovoltaic panel, being in islanded condition. On the other hand, the VSI is used as an active power filter for the reactive power compensation for a grid-connected condition. Simulation results are provided to show the benefits of the proposed controller.
