Microgrids are more likely found on physical terrestrial island nations because typically islands in the tropics have relied on diesel as a fuel source for power. On islands, microgrids have become testbeds to integrate higher shares of variable renewable energy options, such as solar photovoltaic electricity or wind power.
Some islands may be able to accommodate smaller closed-loop pumped storage hydropower systems. The land-use footprint of different storage systems also influences microgrid design on islands. For instance, innovative hydropower and thermal storage may utilize <1 m 2 /kW power capacity (Shan et al. 2022).
In addition, advanced microgrids allow local assets to work together to save costs, extend duration of energy supplies, and produce revenue via market participation. Caterpillar is deploying a 750-kW microgrid on the island of Guam—a challenging deployment environment because of the island power grid and extreme weather phenomena.
For instance, in Bonaire, the microgrid development was a direct consequence of hurricanes and wildfire that presented the impetus to rebuild the electric grid structure using microgrid. Kodiak Island microgrid in Alaska reached 99% renewable electricity integration in 2014 and is one of the larger microgrid systems to serve and island community.
Thus, this paper explores the role that MGs have played in the past and present and what role they could play in the future of small island spaces. It might be concluded that MGs are a key
