AI Technical Summary
Traditional centralized or string DC-AC conversion modules cannot meet the requirements of multi-point grid connection and low-voltage grid connection, and containerized energy storage systems are large in size, which limits their application scenarios.
Design a string low-voltage grid-connected device for an energy storage system. It consists of a power conversion compartment and a transformer compartment arranged horizontally and abutting each other in the AC compartment. The power conversion compartment is equipped with a power conversion module, DC terminals, AC terminals and grid-connection terminals. The transformer compartment is equipped with a transformer. The DC terminals of each energy storage converter are connected to the battery cluster. The control module is used to manage the charging and discharging process of the battery cluster.
It enables low-voltage grid connection and multi-point grid connection, reduces equipment size, improves the charging and discharging efficiency of battery clusters, prevents circulating current, and broadens the application scenarios of energy storage systems.
