Non-divergent state estimator for large scale power systems

INV-19056 Background When solving the power system state estimation problem for very large interconnected systems, certain zones can experience convergence issues for various reasons such as bad data, loss of measurements, topology errors, etc. In such cases, a solution may not be reached by the integrated system state estimator. The purpose of...

Simultaneous detection, identification and correction of network parameter and measurement errors in electric power systems

INV-18007 Background Accuracy of the network parameters has a strong influence on the results of power system state estimation. It has been shown earlier that normalized Lagrange multipliers can be used as a systematic way of identifying errors in network parameters. However, this approach carries a rather heavy computational burden limiting its...
