heal.abstract	This paper presents a hybrid topological-numerical approach for observability analysis in power system state estimation. By partitioning the network in observable areas, a reduced network is formed, where each area is represented by a supernode and each line between areas as a branch. We select as areas the flow islands, being the maximal connected components of flow measured branches. Only	en
