Unbalanced electrical distribution network reconfiguration using simulated anneling

In this article it is presented a methodology for the identification of a reconfigured topology of a distribution system in order to reestablish the energy supply to as much consumers as possible in emergency conditions. It is considered the possibility of switch operations that allow the attendance of security conditions. The approach of the problem was done considering a three-phase and unbalanced formularization of the distribution system. The problem was modeled as a nonlinear mixed integer optimization problem and solved with the heuristic called Simulated Annealing. For evaluation and validation of the methodology an example system was created and used to reproduce critical conditions normally found in real distribution systems.
