针对可再生能源消纳问题,研究了氨能与广义储能参与的多能耦合系统低碳协调运行方式,利用氨能和燃煤机组煤氨混燃相结合的技术来优化系统碳排放。首先考虑氨能参与的多能流交互与广义储能的灵活调控特性,构建了以运行费用最小、可再生能源利用率最大、碳排放量最小为目标函数的综合效益评价指标。提出基于能流关联的碳流拓扑分析方法,利用碳流信息作为综合效益评估的辅助决策手段。最后对实际区域系统进行仿真分析,通过氨能与广义储能的协同调控,有效改善了系统的综合效益。

To address the problem of renewable energy consumption,the low-carbon coordinated operation mode of a multi-energy-coupled system with ammonia energy and generalized energy storage was studied.The combination of ammonia energy and a coal-fired unit of coal-ammonia co-combustion was used to optimize the carbon emissions of the system.First,considering the flexible regulation characteristics of the multi-energy flow interaction and generalized energy storage with the participation of ammonia energy,a comprehensive benefit evaluation index with the minimum operating cost,maximum utilization rate of renewable energy,and minimum carbon emission as the objective function was constructed.A carbon flow topology analysis method based on the energy flow correlation was proposed.The carbon flow information was used as an auxiliary decision-making method for a comprehensive benefit evaluation,and a simulation analysis of the actual regional system was performed.The comprehensive benefits of the system were effectively improved through the coordinated control of the ammonia energy and generalized energy storage.
