Analysis of regional carbon emission flow considering greenpower distribution

Abstract

Most existing carbon emission management is based on macro data statistics, representing carbon emissions generated at the production side by static carbon emissions. It is not easy to describe the transfer and apportionment of carbon emissions. This paper studies the relationship between inter-regional power flow and carbon emission flow based on the theory of carbon emission flow of power system. It simplifies the power system in the region, improves the carbon emission flow index, defines the green electricity distribution factor, establishes the regional carbon emission flow calculation method and the carbon emission flow distribution factor analyzes the correlation between the inter-regional carbon emission flow. Finally, taking a Chinese province as an example, the carbon emission flow distribution and green power distribution between provincial municipalities and outward power coupling to other provinces is calculated to verify the method’s feasibility. The calculation results clearly describe the carbon emission levels of the regional power systems and the distribution of carbon emission flow in the province and analyze the impact of different power generation structures on the distribution of regional carbon emission flow and the contribution of green power. It provides a reference basis for regional emission reduction planning and new energy site selection.
