    Currently, one of the main challenges of solar photovoltaic (PV) systems is to optimize their energy efficiency. Solar panels and dc-dc converters controlled by maximum power point tracking (MPPT) techniques are the two main components of a PV system.To optimize the production of the PV installation, the converter holds pivotal significance. Given its direct impact on the overall performance of the PV system, selecting the appropriate DC-DC converter becomes imperative.This study meticulously compares a variety of non-isolated power converters, encompassing Zeta, SEPIC and Cuk configurations.The input capacitors have been perfectly integrated in all converters, to filter voltage ripple and current ripple. The control of these converters was achieved through the implementation of an incremental conductance algorithm (InCon), improving efficiency and precision. In addition, a meticulously selected irradiation profile was used, to thoroughly test the effectiveness of the system.Our research findings underscore the SEPIC converter's consistent outperformance, showcasing an unparalleled tracking efficiency of 99.01% compared to its counterparts. © 2024 IEEE.

    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.

    High Gain Voltage SEPIC Converter for PV System
    (Institute of Electrical and Electronics Engineers Inc., 2024) Hadji, Slimane; Belkaid, Abdelhakim; Larbi, Lylia; Çolak, İlhami; Kayışlı, Korhan; Aissou, Said
    The main objective of this paper is to propose a modified structure for a SEPIC-type DC-DC converter and to compare it to the simple structure. An incremental conductance (INC) MPPT controller is chosen and applied to both converters in order to extract the maximum available power. The modified converter structure is obtained by adding an inductor and a capacitor to the conventional converter. With this new structure, we go from a step-up/down converter to only a step-up converter. Simulation results, with Matlab/Simulink, illustrate better performances with the modified structure compared to the classical SEPIC structure, less output power oscillation and high voltage gain are guaranteed. © 2024 IEEE.
