ECE Professor Ali Abur was awarded a patent for “Computer-implemented methods and systems for avoiding divergence in multi-area power grid state estimation.”


Abstract Source: USPTO

Divergence of state estimation solutions for multi-area power grids typically occurs due to a single anomaly in the measurement set or network model, yet will cause failure of the state estimator to provide the solution for the entire system. Disclosed herein are methods and systems that allow detection, identification and isolation of the anomaly during the state estimation solution so that a large percentage of the system states can still be estimated, while isolating the anomaly that is causing the divergence for the estimator.
