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 ...
DC power quality emulator
(IEEE, 2020)
Currently, no dc power quality standards exist. The lack of dc power quality (PQ) standards can be addressed by, amongst others, evaluating the impact of PQ deviations on consumer end equipment. A voltage disturbance ...
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 ...
Measurement uncertainty of current harmonics during the assessment of compliance to grid code requirements
(IEEE, 2018)
This paper improves the impact of measurement uncertainty on harmonic grid code compliance assessment by characterization of the current transformers at a renewable power producer. Field data was collected to evaluate the ...
Impact of aggregation interval on harmonic phase angle measurements
(IEEE, 2018)
The aggregation principles of IEC 61000-4-30 is a well-known concept implemented in Power Quality (PQ) recorders. Only rms data is retained. Harmonic emission assessment requires the analysis of harmonic phasors. Continuous ...
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 improvement of system damping by grid integration of PV energy sources
(IEEE, 2017)
The impact of static generators on power system small signal stability is evaluated by means of micro-synchrophasors collected in a distribution system using a class A Power Quality recorder that also functions as a Phasor ...
