Abstract: With the rapid development of smart grid, the optimization and upgrading of distribution network has become an urgent need. In order to meet this requirement, the new distribution network needs to innovate in distributed energy consumption management, interconnection between distribution equipment, and new customer service infrastructure. On the basis of summarizing the key development needs of the new distribution network in detail, the structural characteristics and core technologies of new distribution networks such as distributed microgrid, integrated distribution network, flexible distribution network and flexible distribution network are discussed in depth. It is expected that these analyses can provide useful reference and inspiration for the planning and construction of future distribution networks.
