With the continuous improvement of residents' living standards, the demand for tourism and energy production in cross-border areas gradually forms seasonal characteristics. More and more cross-border regional energy projects adopt a comprehensive energy system composed of various energy forms. However, the multi-energy type regional energy project system is complex, and it is difficult to design, calculate and simulate. In this paper, the energy consumption simulation calculation method of multi-energy type regional energy projects is studied by taking the common cold and thermal power supply system, photovoltaic power generation system, ground source heat pump system, gas boiler and electric refrigeration system as examples, and the integrated energy system simulation calculation platform is developed.
