Microgrid failure is a significant concern in developing countries and rural areas, necessitating effective energy management strategies to enhance post-failure reliability. The battery energy storage system plays a crucial role in microgrids by managing imbalances, mitigating voltages, and improving system reliability. This paper presents a method for optimizing the energy storage system in a photovoltaic-connected microgrid. The method controls battery discharge and charge operations based on load requirements, considering fluctuations in demand over a day. Simulations using MATLAB R2022a employed state flow analysis and linear programming to minimize variable electricity prices before and after islanding events. The results demonstrate significant improvements in energy management by reducing total variable electricity costs. The proposed method enhances the performance and resilience of microgrid systems, addressing challenges associated with intermittent renewable energy and potential system failures. Effective energy storage management enables risk mitigation, improved reliability, and enhanced utilization of renewable resources, ultimately contributing to sustainable and resilient energy systems.
