A Carbon Emission Accounting Model of Transmission Line Considering Measurement Error

Carbon accounting for power grid enterprises is an important way to achieve sustainable development of the power industry, and is also a necessary means to complete the” carbon peak” and ” carbon neutralization” goals. Carbon emission accounting for transmission lines is an important part of them. Carbon emission of transmission lines is mainly caused by line loss. Current statistical line loss is calculated directly from the results of energy measurement on both sides of the line. The error of measurement devices on both sides of the line is not considered, which results in low accuracy of carbon emission measurement. This paper proposes a carbon emission accounting model of transmission lines that takes into account the measurement error and explains the measurement error of the gateway metering device and the calculation method of the combined error, which improves and expands the calculation accuracy and the scope of application.
