针对风电消纳和传统高压储氢方式存储成本较高等问题,提出了一种基于风-氢-甲醇-碳捕集一体化的综合能源系统经济运行模型,实现更为安全经济的储氢模式.首先,构建一体化综合能源系统(integrated energy system,IES)的结构模型,通过氢转甲醇和甲醇重整制氢系统替代传统储氢模式,并与碳捕集设备配合实现碳资源循环利用.其次,综合考虑系统运行经济成本、环境成本,建立了基于风-氢-甲醇-碳捕集一体化的综合能源系统多目标经济运行模型;最后,通过算例对比了 4 种不同的经济运行方案,验证了所提模型的可行性.
Economic Operation Modeling Analysis of Integrated Energy System Based on Integration of Wind-Hydrogen-Methanol-Carbon Capture
Aiming to address the challenge of wind power consumption and high storage costs in traditional hydrogen storage methods,an economic model for integrated energy sys-tems based on the integration of wind-hydrogen-methanol-car-bon capture was proposed to establish a safer and more eco-nomical hydrogen storage mode.First,a structural model of an integrated energy system(IES)was developed to replace the traditional hydrogen storage mode through a hydrogen to meth-anol and methanol reforming hydrogen production system.By Cooperating with carbon capture equipment,carbon resource recycling was realized.Secondly,the economic and environ-mental costs of the system operation were comprehensively considered,leading to the establishment of an economic opera-tion model for the system.Finally,the feasibility of the pro-posed model was verified by comparing four operation scenari-os.
