摘要：AbstractA total least squares approach to estimating the line admittances of an electrical network for power distribution is explored. It is observed that the Newton iterates for solving the corresponding non-linear Karush-Kuhn-Tucker (KKT) optimality conditions are structured for path and tree networks. In particular, it is revealed that a condensed form of the linear system of equations to be solved at each Newton step has a sparse block arrow-head structure, which can be exploited to improve the scalability of the approach. A numerical example for a path network is presented.
