Multi-objective FSC-MPC for single phase three level grid connected F-Type inverter PEMFC system.

The application of model predictive control (MPC) in energy conversion systems has lately attracted a lot of attention, both theoretically and experimentally. To control multi-level inverters in grid-connected operations, different MPC algorithms have been proposed, enabling great performance and quick dynamic responsiveness.The architecture and study of a single three-level grid-connected F-type inverter PEMFC system are presented in this study. A proton exchange membrane fuel cell (PEMFC) is used as an energy producing unit, and the system is connected to the grid through a DC-DC converter and a DC-AC inverter built with the MATLAB-Simulink tool box. To extract the maximum power from the PEMFC we link it with BOOST converte and we apply fuzzy logic (MPPT) during rapid temperature changes. The second part is the inverter which is controlled by a proposed Multi-objective FSC-MPC to ensure excellent ac power quality on the grid side. It is important to provide great tracking effects and robustness. The simulation results show that the proposed method not only completely eliminates or minimizes (THD) of alternating current and also keeps its sinusoidal form with less fluctuation.
