'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...]
Those with ABDR don’t have to cut back on operations to curb use of grid power. Instead, they switch to their on-site generators — likely natural gas — to continue their important work and at the same time receive a demand response payment.
This report details how the integrated power system could look after the full implementation of the proposed plan, when outdated equipment not compliant with the federal Mercury and Air Toxics Standards has been retired and replaced by renewable generation supported by storage.
