Abstract :
A framework for fast decoupled state estimators is presented. Decoupling is not seen as neglecting coupling submatrices in the Jacobian, but as a two-step procedure to solve full-Newton equations, without major approximations. In addition to a sound derivation of the standard version of the fast decoupled state estimator, another version is proposed which presents better performance when applied to power systems with critical r/x ratios. Test results and illustrative examples are presented and discussed
