Abstract
Harmonics brought about by a large number of impulsive and non-linear loads connected to the grid has led to new challenges in regional carbon emission management. The existence of harmonics increases the consumption of power equipment, and the transformation of signal forms makes the accuracy of carbon measurement questioning, which damages fairness and is not conducive to a carbon trading market construction and the purpose of precise carbon verification. This paper proposes that the harmonic level of each node is monitored during carbon metering of the distribution network; carbon metering results are corrected based on the correction amount of harmonic carbon. Harmonic separation and electric carbon conversion of the current-containing harmonic source are conducted on the IEEE-33 node. The results show that harmonic carbon does exist. Carbon metering results are affected when the power quality is seriously distorted, which is not conducive to establishing a carbon metering trading market.
