Energy station and network collaborative optimization planning of park integrated energy system

In order to improve the energy utilization rate of the integrated energy station, a two-layer planning optimization model of the park's integrated energy station-network is proposed from the perspective of the overall station-network planning. The number, location and equipment capacity configuration of the energy station and energy supply network are unified planning and research in this planning model, based on the complementary characteristics of electricity, heat and cooling. The upper layer of the model aims to minimize the comprehensive energy distance and establishes a collaborative investment model for energy station-networks based on the popularization of the p-median model. The lower layer fully considers the multi-energy flow coupling within the energy station and the multi-energy coordination of the inter-station network to establish a multi-energy station planning operation joint optimization model. Using the enumeration method based on the shortest path theory and the CPLEX solver to solve the problem, the energy transfer on the time and space scale is realized, and the problem of uneven load distribution and uneven peak and valley demand in traditional planning is solved. The calculation example shows that the proposed model has practicality and is of guiding significance for the comprehensive planning and construction of the integrated energy park.
