The Carbon Emission Reduction Contribution of Clean Energy Power Generation from the Perspective of Carbon Emissions Flow: Evidence from Pingliang, China

The carbon emission flow of the power system, as a new direction for carbon emission reduction in the power system, provides new ideas for the measurement of carbon emissions in the power system and other issues. This paper aims to propose a method for calculating the carbon emission flow of the power system that takes into account the carbon reduction contribution of new energy, based on the carbon emission flow of the power system, and conducts an empirical analysis in Pingliang City, China. The specific approach is as follows: First, based on the actual network of Pingliang City, the system's power flow distribution is re-determined without considering network losses. Secondly, the carbon emission flow of the network is calculated according to the power flow distribution. Finally, an empirical analysis is conducted through examples, and the results show that the basic method proposed in this paper, which takes into account the output of clean energy in the power system's carbon emission flow, can estimate the carbon reduction contribution of new energy, providing new ideas for the low-carbon development of the power system.
