An architecture for implementing state estimation application in Distribution Management System (DMS)

Abstract

This work aims to propose a state estimation procedure for electric distribution networks and to implement a simulation architecture in order to test it under several scenarios. Measures, obtained from the simulated field through a communication layer, and pseudo-measures, defined according to load and generation models, are combined in different shares to observe the algorithm performances and the effects on the estimation quality. The work also investigates the necessity of a correct load modeling of Medium Voltage/Low Voltage (MV/LV) substations where distributed generation significantly contributes in altering the net power injection at the LV side. The implemented State Estimation (SE) procedure will be installed in a real MV network located in the North of Italy (Sanremo) within a research project.
