The analysis of voltage and current unbalance by application of active and reactive power in the fundamental frequency negative-sequence components
Seiphetlho, T.E.; Rens, A.P.J. (IEEE, 2012)The behaviour of the fundamental frequency negative-sequence power components in unbalanced power networks is evaluated for possible information on the relative contribution by the supply and loading network. Previous ... -
Evaluation of system losses due to harmonics in medium voltage distribution networks
Lombard, C. (Jnr); Rens, A.P.J.; Lombard, C. (Snr) (IEEE, 2016)Power system harmonics are a known cause to failure, disoperation or premature aging of customer's equipment. It also causes additional losses in a distribution network that influence the planning and design of future ... -
Improving dynamic microgrid modelling through the use of synchronised field data
Erasmus, R.J.; Rens, A.P.J.; Van Schoor, G.; Uren, K.R. (IEEE, 2020)Simulation during the design and operation of microgrids should include dynamic phenomena that would be a result of the unpredictable variation in renewable generation and loading. Detailed modelling of different components ... -
Microgrid energy management through levelized cost of energy metric
Swanepoel, C.G.; Van Schoor, G.; Uren, K.R.; Rens, A.P.J. (IEEE, 2020)The abundance of solar energy in Africa provides the ideal opportunity to mitigate the concerns on price, reliability and voltage quality of electricity supply to end-users. Rooftop PV and local energy storage solutions ... -
On the assessment of voltage unbalance
Seiphetlho, T.E.; Rens, A.P.J. (IEEE, 2010)The management of voltage unbalance in a power system is supported by the knowledge on the contribution of a single unbalanced load/source to the total level of voltage unbalance observed at a Point of Common Coupling (PCC) ... -
On-line performance monitoring of a transmission line using synchrophasor measurements
De Jager, F.A.; Rens, A.P.J. (IEEE, 2015)Synchrophasors are increasingly being implemented to improve the understanding of network performance. This paper presents the use of voltage and current synchrophasors in the on-line performance monitoring of a transmission ... -
The validation of single point measurements for the localization of multiple harmonic sources
Serfontein, D.; Rens, A.P.J. (IEEE, 2010)Power quality management requires inexpensive and simple methods for electric power quality monitoring. This paper investigates the validity of single point measurements for the localization of sources of waveform distortion ...
