Microgrids are decentralized and autonomous systems that generate, distribute, and manage power locally. They can be found on islands, as well as on the mainland. Especially islands understand the importance of a clean and reliable energy system, as they often hold a unique ecosystem. However, due to their remote location and scarce resources
