Harmonic emission level assessment method based on parameter identification analysis
IET Generation, Transmission & Distribution, 2019 In this study, a new method for harmonic emission level assessment is proposed. The method is based on parameter identification analysis. The quantitative relationship between standard deviation values of equivalent parameters and harmonic emission levels is studied and discussed through theoretical derivations.

Principal Component Regression and Its Application in Power Harmonic Emission Level Evaluation
IOP Conference Series: Materials Science and Engineering, 2019 Abstract Accurate harmonic emission level evaluation is the basis of distinguishing the responsibility of harmonic pollution between power supply system and consumer. A new harmonic emission level evaluation method via principal component regression (PCR) is proposed in this paper. Firstly, the principle of PCR is analyzed.

A South African review of harmonic emission level assessment as per IEC61000-3-6 [PDF]
, 2015 Large-scale renewable power producing plants are being integrated into South African networks. Network operators need to ensure that Renewable Power Plants (RPP) do not negatively affect the power quality levels of their networks, as harmonics amongst others could become a concern. IEC 61000-3-6 details a method for allocating voltage harmonic emission

Harmonic current emission level assessment of residential loads based on impedance-gathering trend
International Transactions on Electrical Energy Systems, 2017 Summary Because of the widespread application of new energy and power electronic–based residential loads in distribution networks, the impact of collective harmonics cannot be ignored. The harmonic impedance should be evaluated when determining the harmonic responsibilities at the point of common coupling.
