    The large use of microgrids, particularly direct current microgrids, is a global trend driven by the increasing integration of renewable energy sources with energy storage systems. DC microgrids offer the distinct advantage of eliminating harmonics and synchronization challenges, making them a focal point for research and engineering attentions. Considering the intermittent nature of primary renewable energy sources, such as photovoltaic and wind energy, the integration of energy storage systems is necessary to improve the reliability, stability, and overall performance of microgrids. This paper proposes an isolated DC microgrid including a photovoltaic array, a hybrid storage system based on a supercapacitor and battery bank, power electronic converters and a variable load. An energy management system to optimize operation of an islanded DC microgrid is presented. The EMS effectively regulates the DC bus voltage and balances power flow within system. To support the EMS, the test condition considers Maximum Power Point Tracking for the photovoltaic array, state of charge management for the battery and supercapacitor banks and converter control strategies to maintain DC bus voltage stability. © 2024 IEEE.

    Energy management strategy for nano-grid in isolated areas
    (Institute of Electrical and Electronics Engineers Inc, 2024) Amirouche, Elyazid; Benyahia, Nabil; Aissou, Said; Belkaid, Abdelhakim; Çolak, İlhami; Berboucha, Ali
    This paper explores a microgrid comprising two renewable energy sources and a battery storage system. Specifically, a photovoltaic (PV) source employing the maximum power point tracking (P&O and FLC) technique is predominantly utilized, with potential support from fuel cells (FC). Our contribution in this work lies in an efficient management approach aimed at reducing reliance on batteries. This translates to cost reduction and overall system lifespan extension, facilitated by the integration of proton exchange membrane fuel cells. System simulation was conducted using SimPowerSystems Simulink library in the MATLAB environment. A critical analysis of the overall system behavior was conducted, accompanied by the presentation of simulated results. © 2024 IEEE.
