Abstract

This research addresses the study of an electric power generation system using green hydrogen fuel cells. The type of cell chosen uses a membrane as an electrolyte to perform proton exchange (PEMFC). The generation system is complemented by a three-phase hysteresis-controlled inverter. The work aims to evaluate the effect that four different types of strong variations in the three-phase load produce on the generation system. The evaluation is experimental at the simulation level, aiming to analyze the stability and quality of the energy supplied by the generation system. The study is implemented through simulations using MATLAB's Simulink. The research focuses on the regulation of active power by controlling the current in the direct axis (d axis), and the evaluation of the variables is developed in the time domain. The article concludes by observing the effects related to stability and quality through indicators such as settling time, overcurrent factor, and total harmonic distortion index among other indicators obtained from operating signals of the generation system.
