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

Abstract

A carbon emission monitoring method based on carbon emission flow is proposed for the integrated electricity 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 principle 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 established， 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 simultaneously elucidate the temporal and spatial carbon footprint of the system， overcoming the limitations of conventional carbon measurement methods that tend to be overly macroscopic.
