Distributed State Estimation for Bilinear Power System Models Based on Weighted Least Absolute Value
Applied SciencesAccurate, scalable, and outlier-robust state estimation (SE) is critical for large AC power systems with mixed SCADA and PMU measurements. This paper proposes D-BSE-L1, a distributed robust state estimator for the bilinear AC model.
