A Linearization of DFT Spectrum for Precision Power Measurement in Presence of Interharmonics
Jian Liu, Wei Zhao, Jianting Zhao +1
The presence of interharmonics in power systems can lead to asynchronous sampling, a phenomenon further aggravated by shifts in the fundamental frequency, which significantly degra…
Metering Error Estimation of Fast-Charging Stations Using Charging Data Analytics
Kang Ma, Xiulan Liu, Xi Chen +5
Accurate electric energy metering (EEM) of fast charging stations (FCSs), serving as critical infrastructure in the electric vehicle (EV) industry and as significant carriers of ve…
Compressive Sensing Empirical Wavelet Transform for Frequency-Banded Power Measurement Considering Interharmonics
Jian Liu, Wei Zhao, Shisong Li
Power measurement algorithms based on Fourier transform are susceptible to errors caused by interharmonics, while wavelet transform algorithms are particularly sensitive to even ha…
A SVD-based Dynamic Harmonic Phasor Estimator with Improved Suppression of Out-of-Band Interference
Dongfang Zhao, Shisong Li, Fuping Wang +3
The diffusion of nonlinear loads and power electronic devices in power systems deteriorates the signal environment and increases the difficulty of measuring harmonic phasors. Consi…
