Abstract: Renewable Energy Sources (RES) have been increasing interest in research and industry due to the numerous advantages in comparison of AC. “This paper proposes the control algorithm, optimal power management system with battery protection for standalone photovoltaic (PV) system microgrid to decreases its operating & maintenance cost. The microgrid includes PV system and battery. The proposed control strategy consists of three stages: power management system, battery protection and supervisory control. Power or energy management system is responsible for load scheduling power flow between the battery, microgrid sources and loads on economic analysis. Battery protection scheme is responsible for protection of battery from overcharging and over discharging. Supervisory control is responsible for compensate the mismatching power between the schedule power and microgrid power”. The proposed control system is demonstrated via case studies, simulation results with matlab and laboratory experimental setup.
