Digital Twins promise to deliver a step-change in distribution system operations and planning, but there are few real-world examples that explore the challenges of combining imperfect model and measurement data, and then use these as the basis for su

Abstract The supervisory control and data acquisition (SCADA) system is one of the key requirements for monitoring the power systems state. The power system state is estimated from the state estimation (SE) function, which uses the measurements resul

While the phase angle of any of the bus voltages can be chosen as the angular reference in the state estimation formulation of positive sequence networks, the same approach does not readily extend to three-phase network state estimation problem. It i

A centralized framework-based data-driven framework for active distribution system state estimation (DSSE) has been widely leveraged. However, it is challenged by potential data privacy breaches due to the aggregation of raw measurement data in a dat

Distribution system state estimation (DSSE) has been developed for real-time monitoring of distribution systems. As a weighted least square (WLS) based method, DSSE relies on measurement variances to properly weigh the reduction of the measurement re

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
