Modélisation de mini-réseaux autonomes : Intégration des piles à combustible, des électrolyseurs et des panneaux photovoltaïques avec des systèmes de batteries de secours.

Abstract

With the rapid advancement of renewable energy technologies and the growing electricity demand in isolated regions, autonomous mini-grids have emerged as a sustainable and practical solution to current energy challenges. Parametric analysis applied to these systems contributes to enhancing overall performance and improving design accuracy. This study aligns with that objective by simulating an autonomous mini-grid that integrates photovoltaic panels, electrolyzers, fuel cells, a hydrogen storage system, and backup batteries. The analysis is conducted under the specific climatic conditions of the Aïn Témouchent region, using two representative days: December 14th (winter) and June 14th (summer). System modeling was performed using the TRNSYS software, known for its precision in simulating complex energy systems. The results provided a better understanding of the behavior of a solar-hydrogen mini-grid and helped identify potential optimization strategies to improve its energy autonomy.
