is an interesting concept, which has potential to stabilize the electric grid, due to either times of high demand or the variability of renewable energy sources, through the use of automated equipment, turning devices on and off remotely. One element of the smart-grid we often hear about is using power from the batteries in an electric vehicle to supplement power to the grid.
The Smart-Grid requires smart, bi-directional meters, and electronic components that can either charge an electric vehicle OR pull power from it as needed.
At night, an electric vehicle owner charges their vehicle from wall power. At any time that the grid has sudden demand (or a sudden drop in supply) electric power is instead PULLED from the vehicle's battery pack to meet that demand. Electric vehicle owners will be compensated through special electricity pricing for being part of the program. A great deal of infrastructure is required for the Smart-Grid, as well as standardization between vehicle manufacturers, utilities, and interconnected equipment.
The way I see it, the Smart-Grid is a great CONCEPT, but has a number of issues. For example, what if I can't drive as far as I need to in my electric car, because my neighbor was simply being extra-wasteful with his energy use? How much money will it take to set up the Smart-Grid, when we have continually shrinking budgets in government, and much infrastructure that is already behind on repairs and maintenance?
On the other hand, what about a PERSONAL Smart-Grid? A small-scale concept of the Smart-Grid could be designed using little more than hardware-store parts and salvaged materials.
For my project, I required:
An Uninterruptible Power Supply (UPS)
Power cables and connectors (typical hardware store components)
An electric vehicle - in this case, my electric motorcycle
