摘　　要：为了降低综合能源系统(integrated energy system,IES)的净运行成本,提出一种基于Z-score因子的氢电混合IES优化运行增强策略。首先,提出纳入历史价格的Z-score统计度量方法,以实现对氢能的激励作用,降低IES净运行成本。然后,引入平准化储能度电成本(leveling the cost of energy storage,LCOES)和阶梯碳交易理念,进一步增强IES策略优化的效果,提高储能利用率。最后,以低碳经济运行为导向,分析不同能源间的耦合特性,将Z-score因子结合LCOES和阶梯碳交易效用模型协同优化,以系统净运行成本之和最小为优化目标,构建IES低碳经济优化运行模型,运用GUROBI求解器进行求解。算例分析表明,所提策略可使得系统制氢量提升46.27%,净运行成本降低程度在26%至32%之间,在确保经济运行的前提下,显著提高能源利用率,实现IES供需侧的最优匹配,从而为IES低碳经济调度提供参考。To reduce the net operating cost of an integrated energy system(IES),this study proposes an optimization operation enhancement strategy for a hydrogen-electric hybrid IES based on the Z-score factor.First,a Z-score statistical measurement method incorporating historical prices is proposed to achieve an incentive effect on hydrogen energy and reduce the net operating cost of the IES.Second,the leveling cost of energy storage(LCOES)and the concept of ladder carbon trading are introduced to further enhance the optimization effect of the IES strategy and improve energy storage utilization.Finally,guided by the operation of a low-carbon economy,the coupling characteristics between different energy sources were analyzed,and the Z-score factor was combined with the LCOES and ladder carbon trading utility model for collaborative optimization.The minimum sum of the net operating costs of the system is the optimization goal,and an IES low-carbon economy optimization operation model is constructed.The GUROBI solver was used to address this problem.An example analysis demonstrates that the proposed strategy can increase hydrogen production by 46.27%and reduce the net operating costs by 26%-32%.This approach significantly improves the energy utilization rate,ensuring economically efficient operation and optimal matching between the supply and demand sides of the IES,thereby providing a reference for low-carbon economic dispatch in IES.
