Object-oriented (OO) state estimation (SE) is presented, for radial and weakly meshed distribution systems. For radial topologies, the SE problem is formulated as usual; for weakly meshed topologies, closed switches are appropriately modeled in a SE problem formulation suitable for a newly proposed two-cycle method. An OO modeling of the distribution systems is presented, where classes yield the equations that describe the SE problem. The OO implementation of the method is presented. In the case of weakly meshed topologies, it requires some approximations to be introduced, whose infuence on the convergence is investigated. The application of the proposed method and OO implementation to a 69-branch system shows the viability of the approach.
