基于Z-score因子的氢电混合综合能源系统优化运行增强策略
Optimized Operation Enhancement Strategy of Hydrogen-Electric Hybrid Integrated Energy System Based on Z-score Factor
摘要
Abstract
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.关键词
