Estimate the Probability Distribution of Imbalance-Induced Energy Loss With Minimal Data

Imbalance-induced energy loss accounts for a significant part of in low-voltage distribution networks. However, due to the prohibitive cost full monitoring, high-resolution time-series data feeder currents are usually absent accurate computation. This letter presents novel method estimate probability imbalance-induced loss. In proposed method, only line resistance and statistical (mean covariance) phase required imbalanced networks' Furthermore, Bayesian statistics-based data-driven is also get mean covariance value current with minimal measurements. Numerical tests on real three-phase circuit show approach obtains low estimating error field measurement frequency.
