Abstract

Abstract: Distributed energy storage systems have key advantages such as modular design flexibility, bidirectional power regulation, ease of installation, and flexible revenue models, which provides effective solutions for power flow overrun, reverse power flow, and three-phase voltage imbalance in distribution grids. This paper analyzes the application scenarios of distributed energy storage and summarizes the mainstream system architectures of distributed energy storage systems. For the power conversion units within energy storage systems, the current status and advantages/disadvantages of DC/DC and DC/AC converters are discussed. On this basis, the control strategies for DC/DC and DC/AC converters in energy storage systems are analyzed. Finally, it provides an outlook on the future trends of distributed energy storage.

Key words: distributed energy storage, system architecture, power conversion, battery management, control strategy
