As a distribution network grows, the need for voltage control and regulator devices increases, as well as the need for supplying the demands, which assists in monitoring and correction of their magnitudes. Thus, the use of voltage regulators and, more recently, distributed generation applications contribute to the improvement of the process of electric power distribution in order not only to supply the demands, but the quality of the energy supplied. This dissertation presents three three-phase step-voltage regulator models, each of Type B, and two distributed generation models, all of them implemented in a power flow application prepared according to the Backward/Forward Sweep algorithm. The three-phase voltage regulator models differ in their connection, that is, grounded-wye, closed-delta and open-delta, while models of distributed generation are identified by technology and size, being classified into PQ and PV nodes. Results are obtained from three distribution networks for different cases of use of voltage regulators and distributed generation. IEEE 13 and 34 bus systems were used for testing the evaluation algorithm and a 103 bus network, derived form one of the CELG distribution systems, were used as a real case example for the application of the implemented models of voltage regulators and distributed generation. The results were discussed and reviewed so that it is possible to identify the most efficient templates for each case or for the majority of the cases.
