>Plug-in electric vehicles that can pump power back onto the grid
In the not-too-distant future, the so-called smart power grid may want to have a quick conversation with your plug-in electric vehicle.
In a demonstration in Trenton yesterday of emerging technologies that are driving the development of electric vehicles, the University of Delaware and others showcased prototypes that not only draw electricity from the power grid, but also can deliver rapid bursts of power the other way. And the vehicles get paid for that power.
The technology, dubbed Vehicle-to-Grid (V2G), can help grid operators like PJM Interconnection correct short-terms changes in electricity use, an issue that can affect the stability of the power system. Although the problem, dubbed frequency regulation, is largely unknown to the public, it has attracted the attention of grid operators and the Federal Energy Regulatory Commission (FERC).
