Sensitivity Analysis of Stochastic Assessment of Voltage Dips
Paper in proceedings, 2004

This paper addresses the effect of different uncertainties on the stochastic assessment of voltage dip indices. This task is undertaken by introducing site and system indices and performing sensitivity analysis with regard to some uncertainties. Fault rate, fault-type distribution and fault location uncertainties are addressed in this work. Using a reduced model of the Brazilian power system, site and system indices are calculated for a selected number of buses. Relative variations on system and site indices are calculated in relation to a reference case. Results are presented in tables, graphs and figures.
