Performance Limitation of Utility Scale Battery Storage System: Case Study

The deployment of utility-scale battery storage systems is rapidly expanding to facilitate the seamless integration of renewable energy sources into the electrical grid. However, these systems encounter a range of performance constraints, influenced by factors such as temperature, size, and technological limitations, which can have an impact on their operational efficiency and capacity. To ensure optimal performance of BESS, it is essential to establish a comprehensive understanding of the capabilities and constraints of BESS technology, particularly in areas with environmental conditions resembling to those in Dubai. This paper showcases the complete deployment of a Sodium-Sulfur battery storage system seamlessly integrated into the grid, providing essential support to the Photovoltaic (PV) plant generation in Dubai. The study is focused on evaluating the system’s performance by testing a range of operational conditions and detecting any potential limitations. The findings from these tests have been thoroughly examined and are detailed within this paper.
