The ISO/RTO Council has released an excellent report on PEV penetration, its effect on the grid, and expected ancillary services.
Introduction
“The arrival of plug-in electric vehicles (PEVs) to the North American light vehicle market marks the first time since the earliest days of the automotive industry that electricity could be considered a major transportation fuel. The introduction of PEVs also marks a major point of departure for the management of the North American electricity grid with the introduction of a significant new charging load.
While PEVs present a significant new load, they also represent an opportunity to develop existing and potentially new products and services for grid management. In the near term, managed charging of PEVs, coordinated among megawatts of charging load, could help provide ancillary services or emergency reliability services. By using the PEVs’ capability to support two-way power transfers (charging and discharging to the grid), PEVs will serve as a large distributed energy source.”
