Abstract: Proton exchange membrane fuel cells (PEMFC) are a promising renewable energy source, but face challenges like load demand uncertainty and output instability. This research integrates a cogeneration system, thermoelectric generator, and virtual synchronous technology (VST) into a PEMFC system to enhance efficiency, stability, and reliability. Simulation results show a 0.42% increase in electrical efficiency and a 0.16% increase in available energy efficiency compared to traditional PEMFC cogeneration systems. The VST-enabled system exhibits adaptive regulation, reduces harmonics, and improves current and voltage quality. This study represents a significant step toward sustainable and efficient residential energy systems.
