Non-isolated microgrids are those with the possibility of connecting to a larger interconnected distribution system, being able to operate in islanded mode, thus improving service reliability, and also in grid-connected mode, optimizing the operation of its energetic resources through coordinated control to provide electrical and energy services to the distribution system. Two types of laboratory scale operational tests are presented in this work to illustrate the application of non-isolated microgrids with high penetration of distributed energy resources, in order to exemplify the potential for implementing microgrids as an alternative in the network distribution planning, in both urban and rural areas. The tested systems are formed by commercially available equipment, using mature technologies of control, generation, storage and power conversion, so that, from a technological point of view, the strategies exemplified in this work are capable of large-scale implementation in the short term. The test results indicate the potential for adopting microgrids to improve service reliability and reduce operating costs, given the existence of a mechanism for managing local energy resources.
