The role of plug-in hybrid electric vehicles in demand response and beyond

As the electric utility industry continues to move towards becoming more of a deregulated entity, demand response programs are playing a much larger role. Plug-in hybrid electric vehicles (PHEVs) have the potential to increase the ability of residential customers to participate in demand response programs. However, there may need to be changes made in order to incorporate the spatially mobile aspect of PHEVs as new charging infrastructure enables vehicles to charge in many locations. New demand response programs may also be needed to take advantage of the storage potential inherent in the batteries of PHEVs. This paper explores the potential impact of PHEV market penetration on demand response in order to outline the most effective manner of using these resources.
