Least Absolute Value-Based Temperature-Dependent Robust State Estimation

Inaccuracies in both measurements and parameter determination can generate biased results in state estimation. The change in branch temperature precipitates fluctuations in resistance and branch flow measurements. Even when flow measurements derived from remote terminal units are precise, the errone...
