The development of integrated energy systems(IES)can achieve the optimal use of energy

effectively improve the energy efficiency and mitigate the environmental pollution problems. The existing research on the energy station planning of IES mainly focused on the optimal configuration of equipment capacity

and less analysis of the optimal planning of energy station location and pipeline network path is performed. This paper aims at the problem of energy station location selection and optimization layout of energy transmission pipe network considering electricity and heat supply. Firstly

based on the p-median model

an optimal planning model for energy station location and pipe network path layout is established. Secondly

considering the initial investment and construction costs of energy stations and pipe network equipment

an investment cost model of regional integrated energy system is proposed. Finally

the planning model is solved by an algorithm based on the enumeration method. The validity of the model and the algorithm is verified through the simulation of an area.
