Under the background of "dual carbon", in order to reduce the cost of hydrogen energy utilization and the carbon emissions of the integrated energy system, a low-carbon dispatching strategy of green hydrogen and blue hydrogen coordinated integrated energy system is proposed. Firstly, considering the economic and low-carbon complementarity between hydrogen production by electrolysis of water and hydrogen production from natural gas, green hydrogen and blue hydrogen production-storage-use modules are introduced respectively to realize the refined utilization of different types of hydrogen energy. Secondly, the flexibility in hydrogen load supply is analyzed, and the dynamic response mechanism of hydrogen load supply structure is proposed to further reduce operating costs and carbon emissions. Finally, the carbon trading mechanism is introduced to constrain the carbon emissions of the integrated energy system. Based on this, comprehensively considering the constraints of each equipment, the total economic cost of wind power operation and wind curtailment penalty cost, energy purchase cost, blue hydrogen purification cost and carbon transaction cost is the minimum to build a low-carbon economic dispatch model. The CPLEX solver is used to solve the model, and the rationality of the established scheduling model is verified by the comparative analysis of the scheduling results of multiple operating scenarios.
