RT21 | [Chinese] Development and Prospect of DC Distribution Technology

It is an inevitable choice to build a new power system with new energy as the main body to promote the clean and low-carbon development of electric power. For distributed clean energy grid-connected, transmission, consumption and other issues, DC distribution technology compared with the traditional AC power distribution technology is more economical, flexible, reliable. This paper introduces the latest progress of DC power distribution technology research at home and abroad from the aspects of DC distribution system application scenario, system wiring, key equipment, operation control and demonstration engineering, and looks forward to the future key research and application direction.
