Abstract
Existence of leverage points was claimed to be the reason for the WLAV estimator failing to reject bad data in the measurements. This paper presents an impact of leverage points on the result of power system state estimation. State estimator is run with measurement sets with gross error and leverage point. Three test cases are performed and the results are presented using IEEE 30 bus system.
