Calculation and Sharing of Regional Carbon Emission Reduction Considering Construction of Ultra High Voltage AC Projects
Under the"dual carbon"goal,the ultra-high voltage(UHV)AC project,with its advanced technological means,will play a greater role in consuming clean energy and reducing transmission losses.Considering that there is relatively little research on the carbon reduction benefits of UHV AC projects.this paper proposes a quantitative method for evaluating the carbon reduction benefits of UHV AC projects,taking the load landing area as the research object.Firstly,the distribution of power flow at both ends of the transmission and reception is simulated to determine the power flow proportion of the transmission channel.Secondly,an analysis is conducted on the electricity balance of the power supply area to determine the amount of clean energy transmitted by the UHV AC project.The carbon reduction emissions in the load area is calculated based on carbon emission factors,and the Shapley value is used to calculate the carbon reduction benefits of the UHV AC project based on its contribution.Finally,an actual project is taken as an example for numerical analysis.The results indicate that the UHV AC project can reduce carbon emissions by improving the ability to accommodate clean energy.
