Flicker propagation study in a typical Dutch grid

In the last couple of years, the Dutch grid operators register many complaints from the customers about flicker related problems. The power quality monitoring (PQM) in the Dutch grid indicates that the average long-term flicker indicator (Plt) in the low voltage (LV) network has an increasing trend. In this paper a typical Dutch medium and low voltage network is simulated to analyse the flicker propagation behaviour at different parts of the network. The influences of switching of disturbing LV loads on flicker generation (with and without background flicker pollution) are also studied. Further, the flicker transfer coefficients between MV and LV networks are calculated.
