The Utilization of Shared Energy Storage in Energy Systems: A Comprehensive Review

Energy storage (ES) plays a significant role in modern smart grids and energy systems. To facilitate and improve the utilization of ES, appropriate system design and operational strategies should be adopted. The traditional approach of utilizing ES is the individual distributed framework in which an individual ES is installed for each user separately. Due to the cost inefficiency of the individual framework and the difficulty of applying this framework to the grid-scale ES, many studies have suggested the sharing strategy for the utilization of ES to further exploit the potentials of ES. This paper provides a comprehensive review of the papers on shared ES that are published in the last decade. In this review, we characterize the design of the shared ES systems and explain their potential and challenges. We also provide a detailed comparison of the literature on shared ES based on multiple criteria. Finally, we discuss some promising directions for the future study on shared ES.

Automated summary

Energy storage is important in modern smart grids and energy systems, with appropriate system design and operational strategies needed for better utilization. Shared energy storage has been gaining attention in the past decade, offering potential benefits along with challenges that need to be addressed for further development.
