To improve the utilization rate of clean energy, reduce carbon emissions, and alleviate the global energy crisis and greenhouse effect, a low-carbon economic dispatch model of multi-energy park considering high proportion of new energy consumption is proposed. First, after introducing the gas storage and heat storage equipment to the park, the potential of energy coupled devices is further tapped, and the impact of electric vehicle charging mode is explored. Then, based on the stepwise price curve, a price-based integrated thermo-electric demand response model is established. Moreover, considering the low-carbon operation of the integrated energy system, a carbon capture and storage equipment model is built. Furthermore, a mixed integer linear programming model for low-carbon economic dispatch before the day of the multi-energy park is proposed. The example analysis shows that the proposed model can improve the energy utilization rate and the scheduling flexibility of the park, effectively reduce the carbon emissions of the park, increase the income of the park, and promote the consumption of high proportion of new energy.
