Abstract:
      With the transformation of energy cleanliness and the smart energy construction, the DC distribution system (DCS) has been closely watched 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. First of all, the main performance features of the DCS are summarized. Secondly, a comprehensive analysis of the typical topology and power supply pattern in the DCS is carried out, and the control methods of the modular multilevel converter (MMC), DC transformer and low voltage converter connected to the DCS are studied. Finally, combined with the analysis of 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.
