Research on High-Frequency Spatiotemporal Electrical Carbon Intensity

The research on electricity carbon emission intensity has evolved towards greater precision, finer regional granularity, and increased timeliness. This paper introduced a theory of coupled analysis between power flow and carbon flow and pre-sented a method for calculating electricity carbon intensity across various time and space dimensions. Utilizing the constructed “Electricity Carbon One Graph” system, this research acquired spatiotemporal carbon intensity values for a provincial power grid in southwestern China. By comparing carbon emission amounts calculated with different carbon factors based on electricity generation and consumption, this study emphasized the necessity of researching and applying spatiotemporal grid carbon emission factors. It was evident that using spatiotemporal grid carbon emission factors has been the future trend in carbon emission accounting.
