Analysis of Incremental Carbon Emission Flow Intensity in Power System Considering Transmission Loss

Thermal power generation is one of the main sources of carbon dioxide emissions, and load-side allocation of carbon emissions in the power system is an important measure to incentivize enterprises to improve energy efficiency and thereby reduce carbon emissions. Carbon emission flow theory provides a feasible implementation path for carbon responsibility allocation in the power system. This paper analyzes the impact of power system network loss on network carbon emission flow, and proposes the concept of incremental carbon flow intensity accordingly. The concept of node level is proposed to reflect the power system structure, and based on this, the carbon flow intensity of lines and nodes is calculated. The effectiveness of the theory and algorithm is verified by an example system, and a comparative analysis of two carbon emission flow calculations with or without considering network loss is performed.
