초록
This paper is about to the branch topology error identification in electric power systems. Topology errors may cause the state estimators to converge to a wrong solution or in some cases not to converge at all. The branch error identification is carried out as part of the state estimation procedure. The basic idea is that the estimates of these error variables will be insignificant if the branch is modeled correctly and they will be relatively large otherwise. A two step procedure for the identification of faulted branches is proposed.
