Abstract :
This paper extends to the load flow problem the factorized solution methodology recently developed for equality-constrained state estimation. This is done by considering a redundant set of initial conditions in order to transform the undetermined system arising in the first linear stage into an overdetermined one. The second nonlinear stage proceeds exactly like in the state estimation case. Experimental results are included showing that the factorized load flow is more robust than the standard NR method, while remaining computationally competitive.
