Abstract: The future power system will be in the form of regional alternating current（AC） transmission, AC distribution network and direct current（DC） network coexistence. As the middle part of the whole DC system, DC distribution network plays a key role in the connection of high voltage power transmission network and power loads. On the basis of analyzing the drives of DC power distribution network, the paper introduced the development status of DC power distribution in China and abroad. Then the preliminary ideas of three aspects of the future of the power system, the DC distribution voltage level sequence, the typical application scenarios of the DC distribution and the network architecture were presented. This paper also introduced the network topology of the 10 k V DC pilot project of Aachen University campus in Germany. The outline of the future DC distribution network, the development of the energy internet, and the innovative ideas for the construction of new intelligent distribution network were also introduced.
