Abstract

The feasibility of using delayed smart meter measurements for distribution state estimation is investigated. It was assumed that smart meters take local measurements, store them, and transmit a batch of information twice a day. An 11 kV underground network (the UK Generic Distribution Network) with various numbers of distributed generators connected was used for the study. The error and standard deviations of the voltage estimates are reported for a varying number of near realtime measurements from the distributed generators. Simulations results for different loads and generation outputs are also reported. The results shows that the voltages of a distribution network can be estimated reliably by a state estimator using the previous day's smart meter measurements and a small number of near real-time measurements.
