The discrete Fourier transform (DFT) is still a widely used tool for analyzing and measuring
both stationary and transient signals in power system harmonics. However, the …

The article presents the novel findings on the dependence of voltage fluctuation severity on
voltage distortion caused by power electronic loads. The results indicate the need to modify …

In recent years, several countries have adopted measures aimed at improving the efficiency
of energy usage and reducing energy costs. One initiative has been to encourage the use of …

This paper presents the configuration, control, and implementation of a testing device to
check the reliability of a high-voltage high-power distributed generation (DG) grid-connected …

The flickermeter described in International Electrotechnical Commission (IEC) Standard
61000-4-15 is widely used to quantify the voltage flicker level in practical applications. The …

Power system oscillations are a significant concern for system operators, a problem that has
grown due to the interconnection of inverter-based resources. To address this issue, various …

The interharmonic group concept adopted by the IEC 61000-4-7 is very useful for
addressing the need to monitor interharmonics in power systems. This paper shows that …

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 …

Although globally deployed for flicker assessment, the flickermeter presented by
International Electrotechnical Commission (IEC) Standard 61000-4-15 has been proved to …

Accurate tracking and estimation of the voltage flicker levels is important for effective design
and implementations of voltage mitigation devices. This paper presents tracking and …
