Voltage fluctuations in transmission networks caused by the operations of large consumers, for example, electric arc furnaces, are often the primary sources of high levels of flicker at the end-users in low-voltage networks. This article compares two methods for simulating the flicker propagation in a meshed high-voltage network by comparing simulated levels of flicker with levels obtained from field measurements. The simulations were performed by varying several of the parameters in both methods. The comparison of the simulated and measured flicker values was extended to include two different network schemes and provides a further insight into the nature of flicker propagation in power networks.
