Research on the Synergistic Application of Energy Storage Technology and Flexible DC Technology in Rural Distribution Stations

This paper analyzes the application requirements of flexible DC technology and energy storage technology in rural distribution stations, studies the flexible DC-energy storage technology in the station area from the aspects of operation control, design and construction, interconnection topology, and proposes the architecture and construction scheme of the flexible interconnection and energy storage system in the station area by using the flexible DC-energy storage technology. To realize the functions of dynamic capacity increase and fault quick transfer of power supply, further strengthen the stability of power supply and lay a solid foundation for the interaction of rural distribution stations.
