Microgrids are a promising solution for decentralized energy generation and distribution, offering reliability, efficiency, resilience. These small-scale power systems can operate independently or connect to the main grid, providing greater reliability However, integrating renewable into microgrids presents challenges due their unpredictable nature fluctuating load of electricity. Energy management strategies play crucial role in optimizing operation microgrids, aiming balance electricity supply demand, maximize utilization, minimize operational costs. Various approaches have been proposed including optimization algorithms, machine learning techniques, intelligent control systems. This study proposes an optimized efficient strategy operating both independent grid-connected modes, focusing on that utilize combination solar green sources. The approach, based Promoted Remora Optimization (PRO) algorithm, aims meet requirements at lowest possible cost while ensuring constant DC bus voltage safeguarding batteries against overcharging depletion. CRO method effectively charging process, maintaining consistent level charge achieving final SoC 33.37 %-33.60 %.
