Abstrakt: Renewable sources and Distributed Generation (DG) have been generating a growing economic interest given the increase in electricity consumption. For the end consumer, the lower environmental impact, easy-to-install and quick payback are great alternatives to traditional connections. DG growth drives new studies to predict different results in the electrical grid. The IEEE 1547 technical guidelines bring the possibility that in case of any failure that causes a shutdown, the operation is possible through intentional islanding provided by the electrical utility, continuing service, and maintaining customer satisfaction. For a more in-depth analysis of the impacts of this scenario, this paper contributes with a proposal to modify the strategy for identifying possible intentional islanding. A hybrid relay was modeled using passive techniques along with a suggestion for the operation of the newly formed Microgrid (MG), presenting a control philosophy of the regulators connected to the grid or being islanded, the latter defining the functions of the DGs as master–slave. The results obtained by the experiments proved to be excellent when inserting loads while the intentional islanding event occurs, confirming that the model is within the technical guidelines of IEEE 1547. This paper brings exciting conclusions about this operation, and the power quality of the electrical generator in the MG, according to the criteria established by ANEEL's Distribution Procedures Guidelines (PRODIST).
