Predictive current control two step of a single-phase inverter for grid connected PEMFC system

This research presents the design and analysis of a single-phase grid-connected fuel cell system. As an energy generation unit, a proton exchange membrane fuel cell (PEMFC) is utilized, and the system is linked into the grid via a DC-DC converter and a DC-AC inverter using MATLAB-simulink.at the beginning the PEMF connected the DC-DC boost converter, to extract the maximum power we use fuzzy logic (MPPT) under temperature oxygen and hydrogen pressures changes, the second part is the inverter connected to the grid controlled by the proposes an FSC-MPC (finite set control model predictive control) two-step for single-phase grid-tied PEMFC system to assure high ac power quality on the grid side. It is important to provide great tracking effects and robustness. The simulation results demonstrate that the suggested approach can not only entirely remove or minimize the total harmonic distortion (THD) of alternating current on the grid side while maintaining its sinusoidal shape, but it can also improve the system's transient performance.
