摘要：

Static-state estimation frequently involves equality constraints due to the presence of buses with neither load nor generation. Equality constraints are usually treated by using the method of Lagrange multipliers. The resulting system of equations is not only larger than the unconstrained case, but is also indefinite. The method described in this paper avoids computation of the Lagrange multipliers by treating the constraints in a direct fashion. © 1990 IEEE
