The History of Microgrids. Microgrids have a long history originating with Thomas Edison''s first power plant constructed in 1882, known as the Manhattan Pearl Street Station. It essentially acted as a microgrid since the centralized grid was not yet established. By 1886, Edison''s firm had installed 58 direct current (DC) microgrids.
Last fall, the first phase of a resilient DC microgrid project was brought online at Kirtland Air Force Base (KAFB) through a cooperative research and development agreement between Sandia National Laboratories, with funding from the Department of Energy''s Office of Electricity, and Emera Technologies..

In a microgrid, energy storage performs multiple functions, such as ensuring power quality, performing frequency and voltage regulation, smoothing the output of renewable energy sources, providing backup power for the system, and playing a crucial role in cost optimization.
Microgrid technology can also integrate distributed energy resources (DERs) into the grid, including renewable energy sources. Since wind and solar power generation can vary with weather and time of day, it's useful to be able to draw power when they're available but also have other options when they're not.
