电-气互联系统是综合能源系统的重要组成部分,燃气机组是其中关键的能源耦合元件,而随着能源系统低碳化转型,燃气机组掺氢燃烧发电的技术应运而生.传统氢混燃机相关研究大多只考虑固定掺氢比运行的情况,并未考虑机组动态调整掺氢比运行的影响.传统电-气互联系统优化调度相关研究主要面向运行经济性,而对计及氢混燃机的能量与备用统一出清鲜有研究.为此,该文提出了一种考虑氢混燃机动态混氢比的电-气互联系统优化调度方法,基于动态混氢特性建立氢混燃机精细化模型,并通过电解水制氢技术为氢混燃机提供氢气来源,配置储氢罐和储气罐作为联合体为系统提供备用;采用二项式松弛方法对氢混燃机耗气流量方程进行线性转化,将原有非凸非线性模型转化为混合整数线性规划模型求解;最后通过仿真验证所提方法的有效性,分析不同场景下系统运行状态,实现了"风电-电解水制氢-氢混燃机"模式下风电消纳潜力的深度挖掘.
Integrated Electrical and Natural Gas System Optimal Scheduling Considering Dynamic Hydrogen Mixing Characteristics of Hydrogen Mixed Gas Turbines
The integrated electrical and natural gas system is a crucial part of the integrated energy system,in which the gas turbine plays a key role as a coupling component.With the decarbonization of the energy system,the technology of hydrogen mixed gas turbines emerges.he traditional researches focus mostly on the fixed hydrogen doping ratio operations while seldom consider the dynamic adjustment of the hydrogen doping ratios.The traditional researches on optimal scheduling of the integrated electrical and natural gas system are mainly based on the operational efficiency,but with little concern about the energy and the reserve clearing with hydrogen-mixed gas turbines.This paper gives an optimal scheduling method considering the dynamic hydrogen mixing ratios of the hydrogen mixed gas turbines.The elaborate model of the hydrogen mixed gas turbine is established based on the characteristic.The hydrogen production technology based on the electrolyzer provides the hydrogen source.The hydrogen and the gas storage tanks serve jointly as the system reserve.A binomial relaxation method is used to linearly transform the gas consumption flow equation.The non-convex non-linear model is converted to a mixed integer linear programming model for the solution.Finally,the effectiveness of the presented method is demonstrated under different scenarios.The"wind power-hydrogen production by electrolyzer-hydrogen mixed gas turbine"mode is explored to improve the accommodation potential of the wind power.
