摘要：区域综合能源系统（regional integrated energy system，RIES）通过能源枢纽耦合多种能源优势互补，提高能源利用率。考虑能源耦合设备变工况运行对改善综合能源系统优化配置经济性具有重要意义。首先，分析能源耦合设备变工况特性，建立设备变工况动态模型，并改进能源枢纽转换矩阵。其次，基于典型日负荷曲线，建立以系统年化投资最小、系统日运行经济性最优为目标的RIES优化配置模型。最后，结合算例分析了不同场景下容量配置结果和设备出力情况。结果表明，在RIES的优化配置中考虑能源枢纽变工况特性能够有效降低综合能源系统投运成本，利于实现系统合理配置。
Abstract:To improve the energy utilization, regional integrated energy system (abbr. RIES) implement the complementation of the advantages of multi energy sources by the coupling of energy hub. Considering the great significance of variable condition operation of energy conversion equipment for improving the economy of optimal allocation of integrated energy system, firstly, on the basis of analyzing the variable conditions characteristics of energy coupling equipments a dynamic model of the equipment under variable conditions was proposed, and the conversion matrix of the energy hub was improved. Secondly, based on typical daily load curves, an optimal allocation of water resources model for RIES, in which the minimum annual investment of the system and the optimum of daily operation economy of the system were taken as the objectives, was established. Finally, combining with computing example, the results of capacity configuration and equipment output in different scenarios were analyzed. Analysis results show that in the optimal configuration of RIES the consideration on the variable conditions characteristics of energy hub can effectively reduce the cost of putting integrated energy system into operation, so it is beneficial to implement the reasonable configuration of integrated energy system.
