Multi-energy Coupled Flow Hub Modeling for Generalized Energy Quality Analysis
摘要
Abstract
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.关键词
