A novel method for calculating harmonic contribution based on difference recurrence estimation

IET Generation, Transmission & Distribution
Determining the harmonic contribution of each harmonic source is conducive to improving the harmonic management of the power system. The main problem with harmonic contribution calculation is determining the equivalent system harmonic impedance.

Phasor-Based Assessment for Harmonic Sources in Distribution Networks [PDF]

, 2020
Phasor-based interdependencies of multiple harmonic sources, especially Distributed Energy Resources, on distribution networks are analyzed in this paper. A new index, Phasor Harmonic Index (IPH), is proposed by the authors.

Harmonic mitigation potential of shunt harmonic impedances and the influence of background distortion [PDF]

2003 IEEE Bologna Power Tech Conference Proceedings,, 2004
Although complete compensation is only possible using true active filters, shunt harmonic impedances (SHI) have been shown to provide a considerable reduction of the harmonic propagation. In this paper, the mitigation potential of different shunt harmonic impedances is investigated, together with their VA-rating.

Unraveling the Molecular Mechanisms of Glioma Recurrence: A Study Integrating Single‐Cell and Spatial Transcriptomics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.

High-Frequency Resonance Evaluation and Suppression Measures for Receiving-End of Kun-Liu-Long DC Project

Zhongguo dianli, 2022
The voltage source converter is prone to negative damping in the high-frequency harmonic band, thus causing resonance phenomena. The Kun-Liu-Long DC project, as a UHV multi-terminal hybrid DC transmission project, needs to evaluate and analyse the high ...
