A literature review regarding the VSG methods developed, their operating principle and objectives, as well as other components inserted in the context of distributed generation are specified. In addition, methodological procedures are presented, such as mathematical modeling of VSG, PWM modulation to generate sine waves to be inserted in the network and the implementation of a method of connection to the network in order to synchronize components with voltages generated by the VSG. For this, the PLL method was used to connect to the grid, they were used for voltage compensation, synchronism and generator speed control. PSIM® software was used for validation and simulation of the proposed system. Finally, results of VSG simulations, PWM modulation, currents and voltages at the connection point are presented. As result, the system proved to be capable of generating voltages and currents necessary to maintain a desired power flow in the network, presenting a slight error while operating isolated from it, however a practical implementation is possible. Nevertheless, the error presented when connected to a network was greater, due to the open loop power control.pt-BREngenharia ElétricaGerador síncrono virtualTrabalho de Conclusão de Curso
