Carbon Emission Factor Calculation Model of Regional Power Grid Based on Electromagnetic Loop Network Partition

Power supply enterprises carried out carbon emission accounting research earlier. However, the types of power generation consumed by most regions and the types of power generation exchanged are not statistically complete, and the carbon trace is unclear. When calculating the carbon emissions of the power supply at the provincial and regional levels, the unified carbon emission factor of the power supply region is generally used for calculation. There is a significant error between the carbon emissions of the regional power grids in the province and the actual carbon emissions. To improve the accuracy of carbon emission calculation in time and space, based on the current situation of China's power grid, this paper divides the provincial power grid into a main network of 500 kV and above and several 220 kV regional power grids that can be decoupled by electromagnetic loop network partition, and each decoupled power grid exchanges power only through the 500 kV main network. Based on the actual electricity consumption data, the calculation model of the carbon emission factor on the power side of the province and the carbon emission factor model on the power side of each 220 kV regional power grid after the electromagnetic loop network partition are proposed.
