In the traditional methods used for solving this problem new transmission lines and two-winding transformers are commonly used as expansion candidates. However, reconfiguration of existing network has not been considered as a valid solution in the classical models. The Garver test system and a Colombian system are used to show that considering network reconfiguration can reduce investment costs of the transmission expansion planning problem. This work shows that an optimization model that includes conventional candidates and reconfiguration produces better expansion signals in the transmission lines of electric power systems.85-96spaCombinatorial OptimizationMixed Integer Linear ProgrammingNetwork ReconfigurationTransmission Network Expansion PlanningArtigo10.4067/S0718-07642014000100010Acesso restrito2-s2.0-84902108783
