'Air gap microgrids' -- DC microgrids electrically separated from the utility -- open up the opportunity for installing and adapting microgrids with fewer permitting requirements and less strain on the utility’s grid system. North American microgrids are normally connected to the grid with AC coupling. Each item of equipment in the … [Read more...]
Alexis Zeigler describes Living Earth Farm, a conservationist-oriented community in rural Virginia where a DC microgrid provides reliable energy, fossil-fuel free. It's been a windy spring in the Mid-Atlantic. Our neighbors have lost power several times, including a multi-day outage that caused vexation and set the generators abuzz. I live … [Read more...]
There is a lot of talk about solar plus storage. Yet, it's important to know that by adding energy storage with a DC-to-DC converter you can maximize production & profits of installed North America PV base. Traditional storage plus solar (PV) applications have involved the coupling of independent storage and PV inverters at an AC bus, or … [Read more...]
How can we increase the amount of photovoltaic (PV) generation? From this viewpoint, we are overviewing elec- tric facilities from power plants to electric appliances in demand sites. PV modules generate DC electric power. The power should be converted to AC that is synchronized with commercial grids to be transmitted and distributed to demand … [Read more...]
Of all the world’s many industries, gas exploration and oil production (E&P) activities are arguably the most ripe for automation given two reasons: First, technology advancements have far outrun their adoption by an industry that historically has preferred what it considers time-tested oil production methods – even if those include … [Read more...]
Rocky Mountain Institute’s Andrew Allee describes a problem arising out of electrification in Nigeria. Minigrids are electrifying rural areas, but residents do not benefit if they cannot afford appliances.
This paper describes the design and operation of the microgrid installed for the US Department of Defense at Fort Sill, Oklahoma. To learn more about how to design and operating a microgrid download this white paper.
