基于统一功率流的综合能源系统碳流计算方法
Carbon Flow Calculation Method of Integrated Energy System Based on Unified Power Flow
摘要
Abstract
The calculation of the carbon emission flow of an integrated energy system(IES)has been put forward with higher requirements owing to the proposed"dual carbon"goals and the rapid development of IES.Current IES carbon flow algorithms mainly focus on unidirectional coupling systems,and the coupling element is not unified with the carbon flow calculation model of each subnetwork.Therefore,the carbon flow of the cyclic coupling system cannot be calculated.This study proposes a unified carbon flow calculation method for integrated energy systems for the fast and accurate calculation of carbon emission flows in circular IES.The general algorithm proposed first unifies the calculation of power flow in multi-energy coupled systems.Second,based on the properties and characteristics of carbon flow,the calculation models for the energy network and coupling elements are unified,allowing for the distribution of carbon footprint across the integrated energy system.In addition,considering the dependence of carbon flow on power flow,a complex form is used to represent power and carbon flows in this study.The algorithm was applied to both unidirectional and ring coupling systems,and the results demonstrated it to be more practical,faster,and more applicable.关键词
