Abstract

The knowledge of the distribution system state is required to operate management and control issues, such as energy dispatching and protection coordination. The authors have proposed a novel procedure for harmonic source estimation, based on a Bayesian approach, aimed at giving distribution network operators information about the presence of harmonic producing loads, along with a key indication about the reliability of such information. In this paper a traditional Weighted Least-Squares (WLS) approach is also adapted to the harmonic sources estimation problem. Validation procedures are presented. The Bayesian and WLS methodologies are applied to a small distribution network, the obtained results are compared and analyzed.
