    AC Loads Supply Continuity in Connected and Islanded Microgrids Systems
    (2023) Kaddour, Djillali; Belaidi, Hadjira; Belaidi, Dehia; Faouzi, Didi
    In the pursuit of establishing a sustainable and highly reliable microgrid, the continual operation and system dependability in both grid-connected and islanded configurations emerge as paramount objectives. Our vision centers on the implementation of an intelligent Energy Management System (EMS), complemented by cutting-edge optimization techniques and well-suitable resource sizing. These synergistic components empower the microgrid to adeptly manage peak demands, surmounting even the most adverse weather conditions, all the while liberating it from external resources or any additional draw from the grid facility. Conducting a compelling case study, we delve into the efficiency of our EMS algorithm, thoughtfully realized through MATLAB Simulink, by analyzing pertinent load profiles and power consumption data from buildings within our esteemed institution, IGEE (Institute of Electrical and Electronic Engineering). To transcend the confines of conventional grid-tied PV systems Inverter, we ingeniously propose a novel approach, coordinating a Diesel Generator-Photovoltaic panel (DG-PV) synchronization, thereby seamlessly enabling the grid-tied PV system to function in off-grid scenarios. This concept lies in achieving optimal performance through the deployment of uniform Distributed Energy Resources (DERs) sizes for Photovoltaic (PV) and Battery Energy Storage Systems (BESS) in both grid-connected and islanded modes. Supplemented by sophisticated control algorithms and real-time monitoring, the microgrid flawlessly transits between operational modes, ensuring unrivaled efficiency and unwavering dependability.

    Grid-Connected and Grid-Islanded Energy Consumption Management
    (2023) Kaddour, Djillali; Hadjira, Belaidi; Belaidi, Dehia
    Ensuring microgrid continuity and improving system reliability in grid-connected and islanded modes is crucial for a reliable and sustainable power system. With intelligent EMS (Energy Management System), appropriate sizing, and resource optimization, the microgrid can handle the peak demand even under challenging weather conditions, in both (Connected/Islanded) modes without consuming any extra power from the grid facility or any external resources yet maintaining a reliable power supply. In this paper, a case study of load profile and power consumption estimation of some buildings in our institution IGEE (Institute of Electrical and Electronic Engineering) is used to test and illustrate our EMS performance via MATLAB Simulink. The DG-PV (Diesel Generator-Photovoltaic panel) synchronization technique is adopted to overcome the grid-tied PV system limitation and make it functional in off-grid mode. We used The same DERs (Distributed Energy Resources) sizing for (PV and BESS (Battery Energy Storage System)) in both modes, with advanced control algorithms and monitoring to ensure that our microgrid can have the ability to operate in both modes with a smooth transition from one to another. Hence, by improving the overall system reliability and continuity, we can benefit from all the microgrid mode's advantages to make our system work more efficiently and sustainably.
