Originální abstrakt

This paper presents the research of a weighted least squares (WLS) state estimation (SE) analysis, for a real medium voltage (MV) distribution network, equipped with several Remote Terminal Units (RTUs). The study examines the impact of various factors on SE performance, including the handling of virtual measurements, load estimation errors, the number and placement of real meters, and a comparison between radial and ring topology operation. For each analyzed factor, a simulation scenario is described and conducted using a numerical model of the network. A performance evaluation is carried out by comparing the estimation results, with load flow references. The results are presented using the root mean square error (RMSE) metric.
