An Approach to Network Parameter Estimation in Power System State Estimation
In energy management systems, state estimation is a key function for building a network real-time model. This article describes an approach to network parameter estimation. An appropriate method for network parameter error detection, identification, and correction is developed. The method shown is applicable to single as well as multiple parameter errors. An approximate formula for the perturbed pseudoinverse is developed. To speed up operator's decision-making procedure, a network reduction method and a graphical user interface feature is developed.
