Identification and Measurement of Harmonic Pollution for Radial and Nonradial Systems

Method for Estimating Harmonic Parameters Based on Measurement Data without Phase Angle

“…In order to accurately estimate the harmonic responsibility of harmonic sources, experts and scholars have conducted a lot of research [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. These methods can be divided into direct algorithms When the harmonic source on each feeder acts independently, harmonic voltage ( .…”

“…In recent years, research on the division of harmonic responsibilities has been carried out step-by-step. The main assessment methods can be divided into "intervention" and "non-intervention" methods [10][11][12][13][14][15][16][17]. At present, non-intervention methods are more commonly used.…”

A framework for classification of non-linear loads in smart grids using Artificial Neural Networks and Multi-Agent Systems

“…Due to the need to provide electrical energy with quality and to identify possible disturbances, several proposals regarding methods and tools concerning harmonics related to nonlinear loads [5,6] have been proposed. Among various techniques the ones using the classical approach such as least squares calculation [7] and those based on intelligent systems [8] are found in the literature.…”

Harmonic disturbance location by applying Bayesian inference

“…If it is from the utility to customer, the utility is considered to be dominant to the pollution, and vice versa. The harmonic power approach is improved according to [5] in which several concerns are addressed for the application to radial system and a modification is proposed to generalize its application to non-radial systems. Simulations and experiments carried out in [6] present that the single-point strategy can give useful indications for the detection of the dominant harmonic source, upstream or downstream the measurement point.…”
