Variable renewable energy (VRE), such as photovoltaic solar and wind turbines, will
require new approaches to buffering energy within the grid. This must include significant
ancillary services and longer duration storage to buffer seasonal variations in supply
and demand. Such services may be economically provided by leveraging the battery
resources of electric vehicles (EVs) for frequency response and energy storage for
durations of up to a few hours, together with baseload and dispatchable power for
longer duration buffering.
Impact of Electric Vehicle Charging on Grid Energy Buffering discusses the unsettled
issues and requirements needed to realize the potential of EV batteries for demand
response and grid services, such as improved battery management, control strategies,
and enhanced cybersecurity. Hybrid and fuel cell EVs have significant potential to act
as “peakers” for longer duration buffering, and this approach has the potential to
provide all the long-term energy buffering required by a VRE-intensive grid.
