READ MOREMicrogrids are similar, but also have the capability to connect synchronously to a large network. Island grids are typically the result of geographical circumstances that render the connection to a large network costly or even impossible. Microgrids, in contrast, are designed to increase the security of supply in case the large network breaks down.
