Abstract - The use of Battery Energy Storage Systems (BESS) in contemporary smart grids has accelerated due to the growing use of renewable energy sources. Although BESS improves grid resilience, flexibility, and reliability, its power-electronic interface drastically changes fault characteristics and puts traditional protection schemes to the test. Because of bidirectional power flow, decreased fault currents, and frequent topology changes, traditional fixed-setting protection systems are frequently insufficient in smart grids with high BESS penetration. By dynamically modifying protection settings in response to current grid conditions, adaptive protection has become a viable solution to these problems. With an emphasis on adaptive protection techniques, this paper provides a thorough analysis of BESS integration with smart grids. BESS architectures, fault behaviour, protection issues, adaptive protection techniques, communication needs, and upcoming research are all covered in the review.
