Power system voltage stability is a very important aspect of power system study, and loads have a significant influence on it. With an increasing penetration level of renewable generation, it becomes more crucial. This paper applies Morris screening method to rank the power system load model parameters according to their influence on the voltage stability. The Monte Carlo simulation is used to generate uncertainties to reflect the stochastic behaviour of power systems. The ranking has been made for different loading conditions in order to make the ranking applicable most of the time. Several load models have been applied to investigate the influence of different parameters on voltage stability. The results revealed the important load model parameters and important load buses. The reasons of these parameters being more influential have been analysed.
