基于季节性储氨与燃煤机组灵活降碳的综合能源系统容量优化OA

To address the seasonal imbalance of renewable energy and the challenges of low-carbon transition for coal-fired units under the carbon peaking and carbon neutrality goals,this paper proposes a capacity optimization model of integrated energy systems based on seasonal ammonia storage and flexible carbon reduction in coal-fired units.First,a cross-seasonal energy storage system using ammonia as the medium is constructed.Second,a coordinated operation mechanism for green ammonia co-firing in coal-fired units and liquid-based carbon capture is established to enhance the flexibility and deep decarbonization capability of the units.Finally,under a tiered carbon trading mechanism,the optimal capacities of energy storage and carbon capture are determined with the goal of minimiz-ing the system's comprehensive cost.Simulation results show that ammonia storage can reduce the total system cost by 11.57％compared to hydrogen storage,making it an economically viable seasonal energy storage solution.The synergy of ammonia co-firing and liquid-based carbon capture can reduce carbon emissions by 69.77％,significantly improving system flexibility and low-carbon performance.
