摘      要：Accurate topology estimation is crucial for effectively operating modern distribution *** outages in a distribution network change the network topology by disconnecting some parts of the network from the main *** this paper,an outage detection(or topology estimation)algorithm for radial distribution networks is *** algorithm utilizes noisy power flow measurements collected from a subset of lines in the network,and statistical information characterizing errors in forecasting load ***,a sensor placement scheme is *** sensor placement provides critical sensing for the outage detection algorithm so that any number of possible outages in the network can be *** performance of the proposed outage detection algorithm using the proposed sensor placement is demonstrated through several numerical results on the IEEE 123-node test feeder.
