The main microgrid is connected to the grid and starts running

Grid-connected microgrids: Connect to the primary grid, drawing power from it or sending excess power back to it. Remote/off-grid microgrids: Operate independently from the primary power source, continuously operating in “island mode” and relying on local energy. . 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. . In short, it is a local energy system that can run with the main grid or operate on its own, coordinating generation, storage, and loads to serve a defined area. The interaction hinges on controlled exchange of power and data. A microgrid is thus a type of distributed energy resource. [pdf]
