Solar Photovoltaic and Battery Storage Systems for Grid-Connected in Urban: A Case study of Juba, South Sudan

Solar PVs are gaining considerable acceptance because of their ability to convert sunlight directly into electric power. Nevertheless, photovoltaic-generated electricity may fail to satisfy the ever-increasing energy demand because it does not provide a consistent supply that aligns with the needs of consumers. Energy storage has recently gained importance in grid-connected Photo Voltaic (PV) plants to solve this problem. This helps manage loads more flexibly and overcome problems related to power quality faced by grid-distributed networks, thereby making PV plants valuable and appealing. To effectively integrate PV plants and storage systems into the power grid, various techniques for battery management have been developed to create a demand that is more responsive to prices. The lack of supporting policies hinders the wider deployment of PV systems. This study reviews different techniques of configuration and modeling employed for the optimal operationalization of PV grid-tied systems with battery storage. We examined numerous optimization methods and dispatch mechanisms for energy storage that capitalize on battery-operated PV systems' monetary worth. We also discuss the grid-connected PV system-related power quality and control technology challenges. Finally, we explored several functioning and maintenance concerns of battery-operated PV systems and highlighted the financial and ecological advantages of PV grid-tied configuration. This study aimed to review several technical issues related to the condition of PV systems. These issues include energy regulation, various cell technologies, energy management and scheduling methods, reliability, and power quality. The discussion further address how the findings can be adopted for the grid connected system in the urban areas.
