The power industry is the largest industry for coal consumption and carbon emission in China. Real-time, accurate, and comprehensive measurement of electric power carbon emission is the basis and premise for estimating the potential of electric power carbon emission reduction, incentivizing power consumers to reduce carbon emission, and supporting the data foundation of carbon markets. Therefore, based on the “three abilities” principle of “measurability, reportability, and verifiability” proposed by the United Nations Framework Convention on Climate Change, a carbon measurement method for the whole chain of the power system is proposed. The framework is based on the theory of the carbon emission flow for the power system and realizes the “minute-level” real-time carbon measurement and “consumer-level” precise carbon measurement on the generation-transmission-load sides. On this basis, the carbon measurement system for the whole chain of the power system is designed. The basic concept and implementation form of the power carbon meter system are introduced in detail. The simulation verification is carried out based on the actual system operation data and load data of Changzhou City, Jiangsu Province, China. The simulation results verify the effectiveness of the proposed method. Finally, the key issues that need to be further studied in the field of carbon measurement of power system are prospected.
