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 ...
Harmonic emission assessment on a distribution network: the opportunity for the prevailing angle in harmonic phasors
(IET, 2017)
Harmonic emission assessment in high-voltage networks with a number of renewable power plants (RPP)
interconnected is challenging. A sound scientific methodology readily accessible to engineers is needed to validate ...
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 ...
Dc-bus voltage balancing controllers for split dc-link four-wire inverters and their impact on the quality of the injected currents
(IET, 2017)
The increasing share of single-phase distributed generation units in low-voltage grids causes voltage unbalance problems and overvoltages. Therefore, the need for power quality improving control strategies of grid-connected ...
Decongestion of the distribution grid via optimised location of PV-battery systems
(IET, 2017)
In order to achieve the energy targets for 2020, further integration of renewable energy sources is required.
Hence, there was a need to investigate possible solutions to achieve a reliable network without loss of production. ...
