I'm in the process of completing my Master Thesis and I need to model the current harmonics input of large-scale PV plant into the grid. We're talking about 100MW connected to the 110kV line, using EMTP-RV software.
In order to model the current harmonics, I need the magnetization current percentage of each higher harmonic, in respect to the fundamental harmonic (50Hz in my case). I've read the IEC 61000-3-2 standard, but it is applied to the system voltage not less than 220kV, which has stricter limits, compared to the lower, 110kV system.
I would appreciate the guidance on this matter. A reference conference paper/publication or standard would best suit my needs, as I can not just make things up here.
This is how the harmonics are modeled in the EMTP software.
