Effects of load modelling on the behaviour of power systems

This paper describes the influence of the electrical load model on the behaviour of an electrical power system. Seven different load models have been selected and the impact of these models on four aspects of the behaviour of the network has been investigated. The investigation has been performed on the 220 and 110 kV FGO grid, which forms part of the Dutch high-voltage network. If, for a specific study, the nature of the load is unknown, it is recommended to use a load model in which the active and reactive parts are presented by a constant admittance.
