Meter Placement Impact on Distribution System State Estimation

This paper discusses the criteria that must be considered for the placement of new measurements in distribution networks in order to obtain the best state estimation performances. A better network state monitoring will improve all the other network management tasks. The impacts of the measurement device placement on the state estimation accuracy and on the bad data detection capabilities are illustrated. To ease the comparison of different measurement sets, a visualization method of the expected performances of the state estimator is presented. The paper finally gives measurement placement recommendations based from a literature review and our experience gained from simulations.
