Resumen

This study analyzes an electrical power generation system based on green hydrogen fuel cells. A proton exchange membrane fuel cell (PEMFC) has been selected, which enables proton exchange. Furthermore, the generation system is complemented by a hysteresis-controlled three-phase inverter. The main objective is to evaluate the impact of four different types of abrupt variations in the three-phase load. The evaluation is carried out through simulations in MATLAB Simulink, with a focus on active power regulation through direct-axis (d-axis) current control. Finally, the study analyzes the stability and quality indicators of the generator, providing key information on the system's performance under variable operating conditions.
