Grid Integration of Large
Fluctuating Power Generation with Plug-in Vehicles
Center for Carbon-free Power Integration Director
University of Delaware
Because most carbon-free power is today captured
near the surface of the planet, using power
conversion devices that lack inherent storage, their
electrical power output fluctuates at time scales
from seconds to seasons. Where might we find storage
to level these fluctuations? As industrialized
countries electrify the vehicle fleet, as a
byproduct we will create 20 to 50 kWh of
load-proximate storage per adult, connected to the
grid at 3 - 20 kW, yet tapped for mobility on
average only 1 h/d, using on average only 10 kWh/d.
The economic, engineering, policy, and grid topology
rationales for making this storage available to the
electric system are compelling.
This seminar will discuss basic
principles and report briefly on the industrial
consortium working to implement this technology.
