Abstract: The distribution system is evolving into an integrated trading platform for multiple energy including electricity, gas and heat, which is necessary to meet the demand of point-to-point energy transaction. However, the existing dendritic radiation structure of distribution system is difficult to meet the demand. The networking structures and operation modes of honeycomb integrated energy distribution system（HIEDS）are proposed in this paper. First, the networking structures of HIEDS are proposed, including the flexible interconnection mode between microgrids and key equipment such as integrated energy base stations. Then, the optimal operation models of HIEDS aiming at operation economy and load balance are proposed. Finally, the operation characteristics of HIEDS in different scenarios are analyzed through cases, and compared with other typical microgrid interconnection structures. The results show that HIEDS operates more flexibly and can improve the economy and reliability of system operation. The research in this paper provides a theoretical basis for the structural optimization of integrated energy distribution systems.
