Abstract

This study considers the effect of modeling errors upon the real-time calculation of the bus voltages (or static state) of an electric power system. A criterion for evaluating the sensitivity of weighted least squares state estimation is developed, and the method is applied to a simulated model of an actual transmission system. The mathematical aspects of the analysis are discussed, and the experimental results indicate the effects of errors in several types of system parameters.
