In order to improve the energy efficiency of integrated energy stations, from the perspective of the overall planning of the integrated energy station-network, the number, location and equipment configuration of the energy station, as well as the layout of the energy supply network are planned and studied together. Based on the multi-energy complementary characteristics of electricity, heat and cooling, an optimization model of bi-level planning for park integrated energy station-network is proposed. The upper layer takes the minimum of integrated energy distance as the goal, and establishes the collaborative investment model of energy station-network based on the extended p-median model. The lower layer fully considers the multi-energy flow coupling in the energy station and the multi-energy coordination between the stations. It establishes the joint optimization model of planning and operation in multi-energy stations. The enumeration method based on the shortest path theory combined with Cplex solution is used to realize the energy transfer on the scale of time and space,which solves the problems of uneven load distribution and unbalanced peak valley demand in the traditional planning. Cases show that the proposed model has practicability and guiding significance for the planning and construction of park integrated energy system.
