Microgrid: A local energy system that creates, stores, and shares electricity independently. It often uses renewable sources like solar and wind. Microgrids can run on their own and/or connect to the main power grid. Islanded: In renewable energy, "islanded" means a system is operating autonomously, separate from the main power grid.
