Abstract

To achieve diversified utilization of hydrogen in the integrated energy system, a hydrogen-based multi-energy coupling integrated energy system, considering dynamic hydrogen blending in gas turbine units and flexible carbon capture coupled with power-to-gas technology, has been developed. Based on carbon capture, carbon trading, and demand response, a source-load coordinated carbon reduction strategy is proposed to fully explore the system’s low-carbon economic potential. Firstly, models for hydrogen blending in gas turbines and flexible carbon capture are developed, forming a multi-energy coupling model centered on hydrogen energy. Secondly, a load-side demand response model is constructed to achieve peak shaving and valley filling of electric-thermal loads. This is combined with a tiered carbon trading mechanism and carbon capture equipment to achieve source-load coordinated carbon reduction, further exploiting the system’s low-carbon potential. Finally, an optimization scheduling model is established with the objective of minimizing the total operational costs of the system. By comparing various scenarios for comparison, the proposed optimization scheduling model is demonstrated to effectively improve the renewable energy integration, realize source-load complementary coordination, and enhance the system’s low-carbon and economic benefits.
