摘　　要：综合能源系统(IES)的发展有助于提升系统整体能效、促进可再生能源利用。多类异质能的有效能水平、用能不确定性、碳排放强度等关键广义能量品质的问题逐渐凸显,推动了基于能量流、㶲流、熵增流和碳排放流等能源系统“流”建模理论的发展。多能耦合环节决定着IES多能转化和分配过程,是影响IES广义能量品质的关键因素之一。文中在统一精细化、抽象化程度下,给出了多能耦合环节“流”通用元件的定义。基于标准化矩阵框架提出了适用于多种能量品质分析要素的流集线器模型及其计算方法,并探讨了如何根据模型关系矩阵判定的可解性,合理化修正多能耦合环节约束条件,保证流集线器模型存在唯一运行状态。最后,通过算例验证了流集线器模型的有效性。The development of the integrated energy system (IES) helps improve the overall energy efficiency of the system and promote the utilization of renewable energy. The key generalized energy quality issues such as the effective energy level, energy use uncertainty, and carbon emission intensity of multiple types of heterogeneous energy are gradually becoming prominent, which promotes the development of energy system “flow” modeling theories based on energy flow, exergy flow, entropy increase flow and carbon emission flow. The multi-energy coupled link determines the multi-energy conversion and distribution process of IES, and is one of the key factors which affect the generalized energy quality of IES. In this paper, the definition of “flow” general components in the multi-energy coupled link is given under the unified level of refinement and abstraction. And the flow hub model and its calculation method suitable for various energy quality analysis elements are proposed based on the standardized matrix framework, the discussion is made on how to rationally modify the constraint conditions for the multi-energy coupled link and ensure that the flow hub model has a unique operation state according to the solvability of the model relationship matrix. Finally, the validity of the flow hub model is verified through case studies.
