摘　　要：随着混氢天然气技术发展,氢混燃机成为未来电-混氢天然气城市综合能源系统的关键技术节点。为此,该文分别对混氢天然气网和氢混燃机进行特性分析,并搭建考虑多气体组分混合的混氢天然气网与氢混燃机耦合架构。从多学科信息融合角度出发,采用阿伦尼乌斯方程和系统热力学分别对氢混燃机的碳排放和混合燃烧出力特性精细化建模,并基于实例参考范围验证所提模型的合理性。在此基础上,将氢混燃机模型应用到优化调度中,以系统总运行成本最低为目标函数,计及城市配电网、混氢天然气网以及用户单元内部运行约束,建立电-混氢天然气城市综合能源系统优化调度模型。以耦合混氢天然气系统的某实际城市配电网为算例进行验证,结果表明,基于电转气的天然气网掺氢运输和本地储氢供应均能有效提高电网的可再生能源消纳水平,其风电利用率之差不超过2.12%,但前者的总运行成本比后者少4.31%,能够降低系统总运行成本的同时有效促进用户侧低碳减排。With the development of hydrogen enriched compressed natural gas technology,a hydrogen mixed gas turbine has become the key technical node of electricity-hydrogen enriched compressed natural gas urban integrated energy system in the future.To this end,this paper analyzes the characteristics of the hydrogen enriched compressed natural gas network and hydrogen mixed gas turbine,and establishes the coupling architecture of the hydrogen enriched compressed natural gas network and hydrogen mixed gas turbine considering multi-component blending.From the perspective of multidisciplinary information fusion,the refined modeling of carbon emission and co-combustion output characteristics of hydrogen mixed gas turbine is obtained by Arrhenius equation and system thermodynamics,respectively.The rationality of the proposed model is verified based on the reference range of an example.On this basis,the model of hydrogen mixed gas turbine is applied to the optimal scheduling.Taking the lowest total operation cost of the system as the objective function,and considering the internal operation constraints of urban distribution network,hydrogen enriched compressed natural gas network and user units,the joint optimal scheduling model of electricity-hydrogen enriched compressed natural gas urban integrated energy system is established.Taking an actual urban distribution network coupled with hydrogen enriched compressed natural gas system as an example,the results show that the transportation with hydrogen blending in natural gas network and local hydrogen storage supply could effectively improve the renewable energy consumption level of power grid,and the difference in their wind power utilization is no more than 2.12%;however,the total operation cost of the former is 4.31%less than that of the latter,which could reduce the total operation cost of the system and effectively promote the low carbon emission reduction in users.
