Renewable Energy Sources (RES) have seen increasing interest in research and industry due to the numerous advantages compared to AC. Our project reported here proposes a control algorithm for optimal power management system with battery protection for a Standalone Solar Photovoltaic (SPV) system microgrid to minimize its operating cost. The microgrid includes SPV and battery. The control system consists of three stages: power management system, battery protection and supervisory control.The power management system is responsible for scheduling the power flow between the microgrid sources, battery and loads on economic analysis. Battery protection scheme is responsible for the protection of battery from overcharging and over discharging. Supervisory control is responsible for compensating the mismatch power between the schedule power and microgrid power. The effectiveness of the proposed system is demonstrated via case studies, simulation results and experimental setup.
