Works by Celik and Abur suggest a weighted least absolute value state estimation with transformations (WLAV-T) for attaining insensitiveness of state estimation (SE) to bad measurements by mitigating the effect of leverage points. To further improve its applicability, this letter proposes a systematic approach to compute the optimal rotation angles and scaling factors of the WLAV-T, deriving a robust WLAV estimation approach with optimal transformations (WLAV-OT). The proposed approach has been preliminarily tested with promising results.
