'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...]
Pierre Delforge, an NRDC senior scientist, describes an historic decision by the city of Berkeley, California that requires electrification of all new buildings — and the trend it may foretell.
You may have experienced lessons learned while building your microgrid, and there’s more to learn even after your system is online. Download the handbook from S&C Electric designed to guide you through the day-to-day operations of your microgrid and think through long-term needs for microgrid care.
