What is a microgrid?
An EU research project describes a microgrid as comprising Low-Voltage (LV) distribution systems with distributed energy resources (DERs) (microturbines, fuel cells, photovoltaics (PV), etc.), storage devices (batteries, flywheels) energy storage system and flexible loads.
What is a stand-alone microgrid?
A stand-alone microgrid or isolated microgrid, sometimes called an "island grid", only operates off-the-grid and cannot be connected to a wider electric power system. They are usually designed for geographical islands or for rural electrification.
How much does a microgrid cost?
Microgrids are complex systems that require specialized skills to operate and maintain. Microgrids include controls and communication systems that contain cybersecurity risks. A 2018 study conducted by the National Renewable Energy Laboratory found that microgrids in the Continental U.S. cost an average of $2 million-$5 million per megawatt.
