Detection method of interharmonic pairs-caused voltage peak fluctuation flicker
Energy Reports, 2022 Interharmonics of high frequency will cause voltage’s peak value fluctuation, which will result in flicker of fluorescent lamp and LED lamp. To realize accurate evaluation of the flicker, a method based on multiresolution S-transform is proposed to ...

Analytical Frameworks and Theories of Electric Power in Non‐Linear Circuits
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.Based on the challenges of distorted currents and non‐linear components in modern power grids, this article reviews seminal electrical power theories that seek to generalize the traditional definitions of active, reactive, and apparent power. It provides a detailed analysis of their mathematical foundations, practical implementation, and validity.

Sources, Effects, and Modelling of Interharmonics [PDF]
Mathematical Problems in Engineering, 2014 Recently, the increasing use of power electronic systems and time‐variant nonlinear loads has brought number of power harmonics/interharmonics, and the power supply quality is therefore seriously threatened. The presence of interharmonics strongly poses more difficulties in modelling and measuring the distorted waveforms. Therefore, this paper reviews

Towards an EMC Coordination for Interharmonics in Public Low Voltage Networks
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.Flicker in LED lamps caused by interharmonic distortion was identified as a new interference mechanism, which is not yet covered by the existing EMC coordination. Following the process for EMC coordination, the article starts from a detailed characterisation of the new interference mechanism.

Effect of Interharmonics on Flicker of Fluorescent Lamps [PDF]
2018 China International Conference on Electricity Distribution (CICED), 2018 In order to analyze the inter-harmonic affections on the voltage flicker, the relationship between the inter-harmonics and flicker analysis are carried out. In order to be able to accurately determine the level of inter-harmonics to make the electric light flicker, inter-harmonic-flicker limit curve drawing method based on the voltage flicker ...
