What Is a Microgrid? | IBM
Microgrids are small-scale power grids that operate independently to generate electricity for a localized area, such as a university campus, hospital complex, military base or geographical region. The U.S. Department of Energy defines a microgrid as a group of interconnected loads and distributed energy resources within clearly defined
