Abstract

The impending mass electrification of road transport, driven by concerns for climate change and sustainability, enables an opportunity to substantially reduce greenhouse emissions from passenger vehicles and to simultaneously provide services to the electricity grid. Electricity grids are characterised by a lack of storage capacity, which can be provided by grid connected electric vehicles charging and discharging their batteries under centralised control. This paper argues that the Vehicle to Grid (V2G) methodology offers operational, financial and sustainability synergies between vehicles and electricity grids. Broadband communications is an essential service to facilitate the aggregation, distributed control and metering of V2G services. Copyright 2008 Mike Dennis and Bethany Thompson.

Highlights

  • During the 20th century, industrialised countries built two massive energy conversion infrastructures: electricity grids and road transport fleets

  • We argue that broadband communications is absolutely necessary to facilitate future beneficial interaction between electric vehicles and the electricity grid

  • This study shows that plug-in rechargeable hybrid electric vehicles (PHEV), rather than electric only vehicles (EV), technology is the most likely transition platform over the 25 years that our models represent

Summary

VEHICLE TO GRID USING BROADBAND COMMUNICATIONS

The impending mass electrification of road transport, driven by concerns for climate change and sustainability, enables an opportunity to substantially reduce greenhouse emissions from passenger vehicles and to simultaneously provide services to the electricity grid. Electricity grids are characterised by a lack of storage capacity, which can be provided by grid connected electric vehicles charging and discharging their batteries under centralised control. This paper argues that the Vehicle to Grid (V2G) methodology offers operational, financial and sustainability synergies between vehicles and electricity grids. Broadband communications is an essential service to facilitate the aggregation, distributed control and metering of V2G services
