On the assessment of harmonic emission in distribution networks: opportunity for the prevailing harmonic phase angle
(IEEE, 2016)
Harmonic emission assessment for Grid Code compliance of Renewable Power Plants (RPP) has to be fair and pragmatic. The CIGRE C4.109 method lacks the ability to determine which harmonic currents have a positive or negative ...
A discriminative approach to harmonic emission assessment
(IEEE, 2015)
With the onset of renewable power sources onto the network, such as Photovoltaic power plants contributing to Total Harmonic Distortion (THD) in voltage, a methodology to quantify their contribution to the THD in voltage ...
Evaluation of harmonic distortion from multiple renewable sources at a distribution substation
(IEEE, 2017)
Harmonic emission assessment in a distribution network with existing background voltage harmonics is a challenge for Renewable Power Producers (RPP) aiming to achieve grid code compliance. Dynamic interaction of harmonic ...
On the remote calibration of voltage transformers: validation of opportunity
(IEEE, 2018)
Remote calibration of instrument transformers seems possible if sufficient certainty in field measurements can be achieved. This opportunity, until now, was only investigated from a theoretical point of view and in this ...
Field performance of ambient modal estimation in small signal stability
(IEEE, 2015)
Small signal stability is one focus of Wide Area Measurement Systems (WAMS). WAMS systems are becoming more widespread, driven by availability of synchrophasor data from Phasor Measurement Units (PMUs). In this paper, two ...
Improved event based method for harmonic impedance assessment
(IEEE, 2016)
The quantification of harmonic emission requires an accurate model of the network harmonic impedances. A number of techniques have been proposed for the assessment of the network harmonic impedances to be practical and ...
Continuous harmonic impedance assessment using online measurements
(IEEE, 2015)
The quantification of harmonic emission requires an accurate representation of the network harmonic impedances. A number of techniques have been proposed to make the assessment of the network harmonic impedances practical ...
The effect of a reduced power quality on the energy efficiency of stand-alone generator systems
(IEEE, 2016)
It has already been thoroughly validated that the efficiency of direct online motors is susceptible towards certain power quality parameters such as voltage unbalance or harmonic voltage distortion. It can be assumed that ...
Modeling and validation of losses due to unbalanced loading of stand-alone generators
(IEEE, 2017)
The goal of this paper is to evaluate the possibility of deriving a simple lumped electrical model of the additional losses in stand-alone synchronous generators due to unbalanced loading. An in depth analysis will reveal ...
