The assessment of harmonic current emissions produced by inverters is usually based on the assumption, that the grid impedance’s frequency response may be modelled by an ohmic inductive impedance whose parameters are independent of frequency. In order to consider resonance points in the grid impedance’s frequency response, more realistic models of grid utilities are needed. Building models which resemble the frequency behaviour of real points of coupling to the power supply grid is very complex.
