The goal is to find the optimal radial topology that minimizes the power losses. The method is developed in TOMLAB software, and is formulated as a mixed integer quadratic programming problem. Given the current characteristics of the network, the method is based on optimal power flow through DC model. The power losses are given by the Joule effect, calculated according to each distribution line. In order to prove the viability of the obtained results, the proposed methodology is compared with a software used by Portuguese operator for distribution networks planning.engDistribution network reconfigurationNormally open switchOptimal power flowPower lossesjournal article10.1109/PESGM.2016.7741860
