Abstract: Aiming at the problems of insufficient flexibility of traditional low-voltage DC distribution system control and the difficulty of coordinated control of system power flow, the topology structure and system elements of low-voltage DC system were analyzed, and a lowvoltage DC system power flow coordination controller was designed to manage the system's operating status. The device collects and analyzes the operating data of key equipment in the system, and realizes the regulation of the operating status of each device in the system through data communication according to the established strategy. The device was tested in a building's low-voltage DC system, and the operation results show that the device can effectively implement equipment control and power flow management in the low-voltage DC system.
Key words: DC distribution; power flow; coordinated control
