Abstract

This paper analyses the convergence behavior of the least-squares state estimator. It is shown that the standard algorithm based on the Gauss-Newton method ignores second-order information. Under some conditions this information is essential for a good convergence. Examples show that an algorithm based on Newton's method reveals a more robust character. Keywords: least-squares power-system state-estimation; convergence analysis; Gauss-Newton iteration process
