The battle between AC and DC power was decided years ago. When Nikola Tesla and George Westinghouse's AC current became the standard over Thomas Edison's preferred DC current for power distribution, it set the foundation for the electrical infrastructure we have today. And of course that will never change … or will it?
Turn the clock forward 100 years and you will find Ford
One of the problems for AC current is that devices we use run on DC -- so the current needs to be converted. This may not sound like a big deal, but every time you convert electricity or downgrade voltage, you lose a little bit of power. So these microgrids are being built to test whether having a more efficient grid will reduce energy consumption.
The other possible driver is the likelihood that solar power will become a more commonly distributed energy source on roofs of large manufacturing, warehouse, and office buildings. Right now the DC power solar panels generate is converted to AC and back to DC for final use. Staying DC all the way would make a lot of sense if solar power is involved.
This probably isn't welcome news to inverter manufacturers like Power One
This is an interesting development and it will be interesting to see what Ford and Intel find when it is concluded. For now the grid is still under status quo -- but it may be time to shake it up a little bit.
