Abstract—This study aims to explore the importance of Battery Energy Storage Systems (BESS) in the transition to renewable energy, particularly in supporting grid flexibility and standalone applications. It proposes an Energy Management System (EMS) based on using adaptive controls and predictive analysis to optimize the charging and discharging strategies of BESS, thereby improving system efficiency and economic viability. By dynamically monitoring environmental parameters and load demands, the EMS can adjust battery dispatch in real time to maximize the utilization of renewable energy and reduce peak power demand. The results indicate that BESS can effectively balance grid loads, reduce reliance on traditional peak power, and maintain system stability in both gridconnected and off-grid modes. Furthermore, this paper presents recommendations for improving technical, economic, and regulatory frameworks to facilitate the efficient integration of BESS with both grid and off-grid systems, as well as the deployment of renewable energy technologies.
