In this work the problem of the optimal reconfiguration of the transmission network is presented. The way in which the mathematical model used to solve the problem is built is shown, making an extension of the traditional model of optimal power flows, adding binary variables to describe the connection and disconnection of transmission lines (main topic of optimal reconfiguration). A small system of three nodes is used to exemplify in detail the construction of the model to later extend it in the solution of a test system of 14 nodes and another one of 41 nodes (south of Brazil) via an implementation in AMPL using CPLEX. The economic differences of using an optimal reconfiguration model against the traditional solution of optimal power flows are shown with a reduction in the total cost of operation of each system.
