Harmonic load modelling using three methods for Kerman’s power network

Nowadays, power systems have nonlinear loads, which inject harmonics into the system and give rise to non-sinusoidal voltages and currents. The accuracy of harmonic analysis depends on the modelling of harmonic loads. In this study, the sensitivity of three load modelling techniques including Constant Current source, Norton and Conventional load models were evaluated for harmonic producing loads of a system. By using the actual recorded database, harmonic loads of the system were modelled and then the applied models were compared with each other in order to find the most appropriate modelling approach for a part of Kerman’s power network.
