The future electric grid concept will cover some small parts to be disconnected and work in an autonomous way isolated from the main utility. Control of microgrids - composed by the couple distributed sources-local loads - with the competence of operating in grid-connected and island mode is a trending research area. The presence of an efficient algorithm for synchronizing the microgrid with the main grid every time the reclosure is allowed is crucial for assuring a safe operation. The synchronization system presented in this work is compounded by two elements: Dual Second Order Generalized Integrator (DSOGI) and stationary reference frames phase-locked loop (SRF-PLL). Besides, the voltage control of the microgrid plays a great role in the synchronization system performance.
