The electric power system have lines, reactor, regulator voltage, transformer regulator and other elements. These are necessary to carry the energy towards demand electric. The system operate with dispatch economic (DE) where it has the objective function and constrains. However, they DE do not necessary include the minimization power losses that are very import because reduce operation cost. Therefore, in this paper it is realize an optimal location of regulating transformer taps to minimize losses in the electrical system using convex optimization in power flow equations. For this suppose, it take account the bus injection model where it obtain all equations necessary. Then, the model propose are implemented with IEEE 14 bust system test as validation between Digsilent Power Factory and the model implement is of the system electric of Quito city in Ecuador. The result of minimizing lose in optimization process is 0.11 MW.
