| Abstract |
Microgrids, as decentralized production systems, are attracting increasing interest due to their greater efficiency and reliability, helping to redefine the way we approach the transition to cleaner energy. At the same time, sustainable energy resources such as solar, wind, hydro, etc. are positioning themselves as indispensable pillars in this evolution towards a more sustainable energy future. This study focuses on sizing and energy management for an AC microgrid. The system integrates a photovoltaic (PV) source, energy storage sources (ESS) and the distribution grid as a backup source. The main objective is to propose an approach to energy management using fuzzy logic to ensure stable energy distribution between renewable sources and loads, guaranteeing an efficient, sustainable and reliable power supply. A dimensional analysis was carried out using Homer Pro software for the region of Oujda, Morocco, followed by a temporal simulation in the Matlab/Simulink environment. This simulation confirmed the ability of the microgrid to operate safely, while guaranteeing the efficiency of the energy management system employed. Parameters such as photovoltaic energy availability, load demand, and battery state of charge are taken into account to optimize the power supply. This research makes a significant contribution by demonstrating the viability of an AC microgrid and developing an energy management system that will be implemented in a future scaled-down laboratory prototype. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024. |
