Types of microgrid connections

Off-grid microgrids are constructed where there is a significant need for electricity but no access to a wide-area electrical grid. Islands that are too far from the mainland are typically served by their own microgrid. In the past, island microgrids were usually built around diesel or heavy fuel oil generators. While easy to transport.
