Abstract

This paper compares three different methods for a single-point assessment of harmonic contribution from customer installation in terms of their suitability and accuracy for a network-wide evaluation of harmonic distortion levels. The analysis is performed on a benchmark network model (BNM) recently introduced by IEEE PES Task Force on Harmonic Modelling, Simulation and Assessment, which has three customers connected to three PCCs and also features background distortion. The paper shows how the total harmonic distortion at three PCCs can be disaggregated into network (or “true background”) contribution, considered customer contribution, and contribution of all other connected customers. The presented results allow to compare how different methods evaluate effects of harmonic interactions between the network and customers, as well as between different customers in terms of harmonic cancellation, attenuation, summation and resonances.
