    Abstract:

    With the transformation of energy cleanliness and the construction of smart energy, the DC distribution system(DCS)has been paid close attention for its advantages of facilitating the reception of the distributed clean energy and easy control of power. This paper reviews the research status and development trends of the networking technology and application research of DCS. Firstly, the main performance features of the DCS are summarized. Secondly, a comprehensive analysis on the typical topologies and power supply patterns in the DCS is carried out, and the control modes of the modular multilevel converter(MMC), DC transformer and low-voltage converter are studied when these converters are connected to the DCS. Finally, combined with the analysis on the application scenarios and development trends of smart energy such as AC/DC hybrid distribution network, DC energy router, energy internet and ubiquitous power internet of things, the main research directions of the key technology of flexible DC power distribution technology are summarized and forecasted.
