A carbon emission monitoring method for integrated energy systems based on carbonemission flow

针对电-气耦合的综合能源系统,提出了一种基于碳排放流的碳排放监测方法,将发电侧碳排放分摊到各节点负荷与各支路功率上,从而实现碳排放的准确追踪与溯源。首先介绍了碳排放流原理;接着研究碳排放流在电网及气网中的应用,建立电网及气网碳排放监测模型,并基于碳排放流理论提出一种碳排放监测方法;最后通过仿真表明,该综合能源系统碳排放监测方法能够同时表明系统时间与空间上的碳足迹,克服传统碳计量方法统计过于宏观的局限性。

A carbon emission monitoring method based on carbon emission flow is proposed for the integrated elec⁃tricity and gas systems(IEGS).This method distributes carbon emissions on the generation side to various node loads and branch power,thereby achieving accurate tracking and traceability of carbon emissions.Firstly,the prin⁃ciple of carbon emission flow is introduced.Subsequently,the application of carbon emission flow in the power grid and gas network is investigated.A carbon emission monitoring model for the power grid and gas network is estab⁃lished,and a carbon emission monitoring method is proposed based on the theory of carbon emission flow.Finally,simulation results demonstrate that this carbon emission monitoring method for the integrated energy system can si⁃multaneously elucidate the temporal and spatial carbon footprint of the system,overcoming the limitations of conven⁃tional carbon measurement methods that tend to be overly macroscopic.
