Abstract
The power industry is responsible for approximately 40% of the country's total carbon emissions. Therefore, reducing carbon emissions in the power industry is crucial to completing the carbon emission peak and carbon neutrality goals. The average carbon emission factor of the power grid refers to the carbon emissions per unit of power supply in the regional power grid, which is a key indicator for accounting for indirect carbon emissions from electricity consumption in Scope 2. The China has established an ultra-high voltage AC and DC interconnected power grid. The calculation of the average carbon emission factor of the power grid is affected by the received electricity, and the amount of green electricity traded within and between provinces is increasing year by year. The transfer of green environmental benefits caused by green electricity trading also impacts the calculation of the average carbon emission factor of the power grid. Therefore, accurately and scientifically calculating the average carbon emission factor of the power grid based on the physical topology of the interconnected power grid is essential, taking into account the inter-provincial transmission capacity and green electricity trading capacity. This paper proposes a method to calculate the average carbon emission factor of interconnected grids based on the average carbon emission factor of grids published by IPCC and considering the rules of green electricity trading. The average carbon emission factor of 27 provincial and 6 regional grids under State Grid Corporation is calculated, and the feasibility and accuracy of the method are verified using statistical data from the China Electricity Council.
