Abstract-

The increasing penetration of power export corridors and renewable generation has intensified concerns related to transient voltage and frequency stability in large-scale interconnected power systems. To address these challenges, extensive research has been reported on the application of Battery Energy Storage Systems (BESS) and Flexible AC Transmission System (FACTS) devices such as Static Synchronous Compensators (STATCOM). This paper presents a comprehensive review of existing studies focusing on the role of BESS and STATCOM in improving transient stability performance and enhancing power transfer capability between interconnected transmission networks. Particular emphasis is placed on control strategies adopted for BESS, including proportional–integral (PI), PI-lead, and lead–lag controllers, and their effectiveness in maintaining voltage and frequency regulation within permissible battery state-of-charge limits. Reported investigations based on benchmark transmission networks, including equivalent large-scale grids, are analyzed in the context of grid code compliance under various temporary and permanent fault conditions. Additionally, the impact of sequential disturbance events and increased power export levels on system stability is discussed. The comparative assessment highlights that BESS can provide effective support during severe disturbances, especially under scenarios involving reduced availability of reactive power compensation devices such as STATCOM. Furthermore, literature indicates that advanced control schemes for BESS exhibit superior transient response characteristics compared to conventional control approaches. The review identifies key research gaps and motivates further detailed simulation-based investigations for coordinated stability enhancement in modern power systems.
