Common examples include solar photovoltaic (PV) panels, wind turbines, and sometimes, depending on the island's geology, geothermal power plants or wave energy converters. Biomass generators, utilizing locally sourced organic matter, can also be part of the mix. Microgrids exist in three distinct types: grid-connected, islanded, and hybrid configurations. Understanding three types of microgrids helps identify optimal systems for specific applications. They have a physical connection to the utility grid. In its simplest statement, an Island Microgrid is a localized energy grid, distinct from larger national power networks, designed to power a geographically isolated area, commonly an island or remote community.
