摘　　要：为了解决综合能源系统(integrated energy systems,IES)中因能源矩阵之间的相互联系以及多级能源网络之间的耦合关系复杂、难以精细化测算IES总碳排放的问题,提出了一种基于全生命周期法(life cycle assessment,LCA)的含氢能梯级利用的IES优化调度模型。建立了含制氢、用氢以及氢储阶段的氢能梯级利用模型,有效减少了能量梯级损耗;运用LCA精细化计量电-热-气-氢能源网络全周期的碳排放总量;将阶梯碳权交易引入IES优化调度策略中。以系统总成本最小为目标,运用CPLEX对建立的IES低碳经济优化调度模型进行求解。通过对比不同场景,并分析了不同掺氢模式、不同掺氢比对IES低碳经济性的影响。分析结果表明,所提模型在碳排放量、运行总成本以及弃能率方面均显著下降,从而验证了所提模型的有效性。To address the issue of accurately calculating the total carbon emissions of integrated energy systems(IES)due to the complex interrelations between energy matrices and the coupling relationships among multi-level energy networks,a hydrogen-based cascaded utilization IES optimization scheduling model based on the life cycle assessment(LCA)method is proposed.A hydrogen cascaded utilization model that includes hydrogen production,hydrogen utilization,and hydrogen storage stages is established,effectively reducing energy cascaded losses.The LCA method is used to precisely measure the total carbon emissions of the electric-thermal-gas-hydrogen energy network throughout its entire life cycle.The stepped carbon trading is introduced into the IES optimization scheduling strategy.With the goal of minimizing the total system cost,the CPLEX is used to solve the established low-carbon economic optimization scheduling model for IES.By comparing different scenarios,the impact of different hydrogen blending modes and hydrogen blending ratios on the low-carbon economy of IES is analyzed.The results show that the proposed model significantly reduces carbon emissions,total operating costs,and energy abandonment rates,thus verifying the effectiveness of the proposed model.
