Abstract
Transmission network security of supply has been challenged by the inclusion of renewable energy sources. By enhancing network flexibility and reliability, Battery Energy Storage Systems (BESS) have emerged as a possible response to these issues. The study suggests a probabilistic evaluation approach to determine if BESS improves transmission network supply security. The approach considers various BESS power rating and energy capacity combinations to handle peak demands and improve supply security in transmission networks. According to the research, the size of the BESS enhances power supply reliability. Power system planners and regulators can utilise the suggested evaluation process and results to decide how big a BESS should be for a certain transmission network. Additionally, the BESS integration has the potential to enhance transmission network supply security and facilitate the transition to a more robust and sustainable power system. The ability of BESS to store excess renewable energy and release it when needed not only enhances supply security but also enables
a higher penetration of renewable energy sources in the grid. In summary, this research offers an innovative approach for assessing BESS's efficiency in raising supply security in transmission networks. This technique offers useful insights into the ideal size of BESS for a particular network by considering various situations and system
settings. This study can help create more secure and sustainable power systems in the
future and has significant policy and planning implications for the power sector.
