Validation of aggregated harmonic current source models based on different customer type configurations

Deterministic aggregated harmonic source models for harmonic analysis of large medium voltage distribution networks

“…Conference paper [3] has a similar topic, but a different focus, and it presents the results, unpublished elsewhere, related to the analysis of propagation of harmonic voltages between different nodes in MV network. This study both improves and extends significantly the analysis published in conference papers [2, 3]. This work was carried out in order to obtain the results of the harmonic voltage values in all the nodes in a large real MV distribution network, as an input needed for the optimal PQ monitor placement algorithm.…”

“…2 presents the structure of this network by a geographical diagram with feeder colouring. Table 1 gives the length of overhead and cable lines, as well as the number and installed power of 30/0.4 kV distribution transformer substations, for all the feeders in the network [2, 3].…”

“…Other customer categories that can be sources of harmonics in electricity distribution networks include photovoltaics (PVs), electric vehicles (EVs), public lighting, mobile phone base stations etc. [2, 3].…”

“…For harmonic voltage studies in AC electricity distribution networks, there are two types of harmonic sources: (i) background harmonics from higher voltage levels coming from harmonic emission in other connected networks and (ii) harmonic emission of loads connected to the considered network. Background harmonics are usually modelled as background harmonic voltage source, while harmonic emission of loads is usually modelled as a harmonic current source [2, 3]. In large medium voltage (MV) distribution networks, modelling of harmonic sources is especially challenging due to the presence of a large number of different harmonic sources in the network having an influence on harmonic voltage distortion.…”

“…The first results of this work, related to the deterministic methodology of aggregate harmonic source modelling using only the method according to the IEC 61000‐3‐6 summation law, were published in a conference paper [2]. Conference paper [3] has a similar topic, but a different focus, and it presents the results, unpublished elsewhere, related to the analysis of propagation of harmonic voltages between different nodes in MV network.…”
