The integrated energy system is the concrete realization of the energy Internet in the region by coupling various energies and carrying out multi-dimensional coordinated management and distribution of various energies such as electricity, gas, cold and heat. An Integrated energy system planning method is proposed. Firstly, a heterogeneous energy network model of a typical integrated energy system is developed. Aiming at minimizing the total operating cost and maximizing the integrated energy efficiency of the integrated energy system, NSGA-II algorithm is used to realize optimization in MATLAB program. Through the TOPSIS method, multiple sets of solutions are compared and analyzed, thus the optimal planning scheme of the system is obtained quickly and accurately. Through optimization calculation, the optimal capacity allocation and operation strategy of major equipment can be obtained. On the premise of meeting users’ various energy demands, the system investment and energy consumption cost can be reduced to the maximum extent, and the efficient utilization and sustainable development of various energy sources can be promoted.
