What is a microgrid? Benefits, Types, and Applications
A microgrid is a localised and self-contained energy system that can operate independently from the main power grid (we call this off-grid mode) or as a controllable entity with respect to the main power grid (on-grid mode). It consists of distributed energy resources (DERs), such as solar PV plant, wind turbines, storage systems such as ...
Microgrids | Grid Modernization | NREL
NREL has been involved in the modeling, development, testing, and deployment of microgrids since 2001. A microgrid is a group of interconnected loads and distributed energy resources that acts as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to operate in grid-connected or island mode.
