Microgrid (MG), which combines renewable energy sources, energy storage devices, and loads, has lately gained attention as a sustainable energy alternative for mitigating climate change. MG may operate in grid-connected or islanded modes based on upstream grid circumstances. The energy management and control of the MG are important to increase the power quality of the MG. This study provides a MG system consisting of a 60 kWp Si-mono photovoltaic (PV) system made of 160 modules, and a Li-ion battery energy storage system (BESS). Moreover, each unit was linked to the DC bus throughout the DC/DC converters and DC/AC central inverter. The suggested system control relied on harnessing renewable energy to provide loads effectively and monitor battery charge. Simulation findings using MATLAB Simulink show the performance of the suggested microgrid stability solutions. The PV system was controlled by maximum power point tracking-based fuzzy logic (FL-P&O). In addition, the BESS with its battery management system (BMS) using the PI controller was used to stabilize the bus voltage within reference value at variations of irradiance. The MG was connected to the DC side by a voltage source converter (VSC) which is controlled by the hysteresis current control technique. Finally, the DC bus voltage was kept constant at 700 V to preserve the microgrid's balance under different environmental conditions with a minimum value of THD 3.7% in the injection current.
