With the depletion of fossil energy and the popularity of renewable energy, a comprehensive energy system with the goal of improving system energy efficiency and consuming renewable energy is booming. Based on the combined heat, power, and heat generation, this paper builds a comprehensive energy system operation optimization model in conjunction with ground source heat pumps. It aims to find the optimal operation strategy based on the actual situation of the park’s load, equipment capacity, and energy prices. Using the linear programming method, a mathematical model with the best economic efficiency of the integrated energy system is established, the optimal operation strategy for a typical day is analyzed, and the annual operation is simulated. Finally, it compares with conventional energy supply methods and analyzes the contribution to the consumption of renewable energy.

In order to solve the problem that most of the existing combined cooling, heating and power integrated energy systems only consider the investment cost of the system unit or the system environmental pollution affecting the overall optimization of the system, with the goal of system economy and environmental protection, the construction of gas turbines, gas boilers, The optimization model of the combined cooling, heating and power system of electric refrigerators and other units and the establishment of constraint conditions; according to the requirements of the cooling, heating, and electric loads in the dispatch cycle, as well as the energy supply efficiency of each equipment of the system, the starting and stopping power and other operating parameters are in the interval. Based on the respective data, a multi-energy flow regional integrated energy system economic dispatch optimization operation strategy optimized within the dispatch period is proposed. The results show that the operation strategy can take into account the economy and environmental protection of the system at the same time, make the system operation more optimized.
