Abstract

To improve energy utilization efficiency and accelerate the low-carbon transformation of China’s energy structure, a low-carbon economic model for integrated energy systems incorporating advanced adiabatic compressed air energy storage and biomass gas was constructed. First, an advanced adiabatic compressed air energy storage and combined heat and power coupling collaborative heating model was established to achieve heat-power decoupling. Second, a biomass gas multi-energy coupling model considering fermentation temperature factors was constructed, which improves biomass energy utilization while producing natural gas in a more economical and efficient manner. Meanwhile, entropy weight-based information gap decision theory was introduced to objectively describe the uncertainties on both source and load sides. A low-carbon economic dispatch model for integrated energy systems considering stepped carbon trading mechanism and source-load uncertainties was established. The multiple scenarios are established for comparative analysis to validate that the proposed model can enhance economic benefits.
