Calculation of flicker propagation in part of the Slovenian network with voltage interharmonics

The assessment of flicker levels in the Slovenian power network is vital, as flicker is a major power quality concern. The paper shows a method of flicker propagation and summation calculation with network interharmonics on a practical example case of two arc furnaces as major flicker-sources. The example shows flicker propagation in the transmission network and further into the distribution network.
