| 摘要: |
| 混氢天然气(HCNG)技术可有效解决大规模电制氢面临的纯氢运输成本高的问题。针对大规模风光消纳与城市综合能源系统(UIES)低碳优化调度问题，在源-网-荷-氢协同优化框架下，提出考虑电-氢-HCNG耦合与需求响应的UIES低碳优化调度方法。对电-氢-HCNG耦合单元运行特性进行建模，并引入用户单元需求响应机制，以系统运行成本最小为目标，建立UIES低碳优化调度模型。通过算例分析对所提模型进行验证，结果表明电-氢-HCNG耦合单元与用户单元需求响应机制的引入能够有效促进风光消纳，提高UIES低碳性。 |

| Abstract: |
| Hydrogen enriched compressed natural gas(HCNG) technology can effectively solve the problem of high transportation costs of pure hydrogen faced by large-scale power to hydrogen. For the problems of large-scale wind-solar consumption and low-carbon optimal scheduling of urban integrated energy system(UIES),a low-carbon optimal scheduling method for UIES considering electricity-hydrogen-HCNG coupling and demand response is proposed under the framework of source-network-storage-hydrogen collaborative optimization. The operating characteristics of electricity-hydrogen-HCNG coupled unit are modeled, and the demand response mechanism of the user unit is introduced to establish a low-carbon optimal schedule model of UIES with the objective of minimizing the system operation cost. The proposed model is verified by case analysis, and the results show that the introduction of the electricity-hydrogen-HCNG coupling unit and the user unit demand response mechanism can effectively promote wind-solar consumption and improve low-carbon nature of the UIES. |
