What is the grid-connected startup of a microgrid

Grid-connected microgrids: They have a physical connection to the utility grid through a switching mechanism at the point of common coupling (PCC); however, they can be disconnected into island mode and reconnected back to the main grid when required. . A microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. [1] It is able to operate in grid-connected and off-grid modes. [2][3] Microgrids may be linked as a cluster or operated as stand-alone or isolated microgrid which only operates. . NLR has been involved in the modeling, development, testing, and deployment of microgrids since 2001. [pdf]
