Compared with the traditional energy network, the equipment capacity problem of energy interconnected distribution network which involves in electricity network, thermal energy network and natural gas network is comprehensively considered in this paper. On this basis, firstly, the operation architecture of energy interconnected distribution network is designed. Secondly, taking the grid connection location and configuration capacity of key equipment in the system as the control variables and the operation cost of system comprehensive planning in the whole life cycle as the goal, the equipment location and capacity optimization model of energy interconnected distribution network is established. Finally, an IEEE 33 bus energy mutual distribution grid system is taken for example analysis, and the improved chaotic particle swarm optimization algorithm is used to solve it. The simulation results show that the method proposed in this paper is suitable for the equipment location and capacity planning of energy interconnected distribution network, and it can effectively improve the social and economic benefits of system operation.
