Hydrogen is considered a promising alternative to fossil fuels in integrated energy systems (IES). In order to reduce the cost of hydrogen energy utilization and carbon emissions in IES, this paper proposes a dispatching strategy that coordinates green hydrogen and blue hydrogen in IES. This strategy takes into account the economic and low-carbon complementarity between hydrogen production through water electrolysis and natural gas. To ensure the refined utilization of different types of hydrogen energy, the paper introduces the green hydrogen production-storage-use module (GH-PSUM) and the blue hydrogen production-storage-use module (BH-PSUM). Additionally, the paper analyzes the flexibility in hydrogen load supply and proposes the dynamic response mechanism of hydrogen load supply structure (DRM-HLSS) to further reduce operating costs and carbon emissions. Furthermore, the paper introduces the carbon trading mechanism (CTM) to control the carbon emissions of the integrated energy system. The paper establishes a low-carbon economic dispatch model by comprehensively considering the constraints of each equipment and minimizing the total economic cost of wind power operation, wind power curtailment penalty cost, energy purchase cost, blue hydrogen purification cost, and carbon transaction cost. The rationality of the scheduling model is verified through comparative analysis of the scheduling results under multiple operating scenarios.
