THE REAL CONFIDENCE-INTERVALS IN STATE ESTIMATION

The computation of the confidence intervals has been proposed in this paper. Two methods are developed for this purpose. In the first method the confidence intervals are evaluated by calculating the variance of the estimation errors, the differences between the true and the estim ated values. While in the second method, the confidence intervals are evaluated depending on the Lip-to-date results of the state estimation . Both methods are tested using a measuring system for the IEEE-14-Bus -Test-Network with the aid of the Monte-Carlo-Simulation-Technique.
