While the deployment projections of PEVs indicate slow and progressive development over the next 5 to 15 years, PEVs will have high probability of success and significant impact on electric systems. Plug-in vehicles are being developed by many of the global automobile manufacturers: General Motors, Mitsubishi and Nissan have launched the sale of their first production vehicle in 2011. Others, including Ford, Toyota, and BMW, will deploy models in 2012. Much work is going on to optimize engine and battery functions for efficient operation both during vehicle discharge and when grid electricity is available for recharging. The ability of our electric grids to optimize this new and unique energy resource will depend on the speed of deployment of electric vehicles and the ability to either directly control or properly incent through markets the charging and/or discharging of electric vehicles.
It is important to understand the ramifications of introducing a number of plug-in hybrid vehicles onto the grid. Depending on the time and place of adding these vehicles, they could cause new local or regional constraints on the grid. They could require the addition of new generation capacity, increases to the utilization of existing capacity, or a mixture of both. Reserve margins may be reduced if capacity does not keep up with the added demand that these vehicles would add to the grid, resulting in reliability concerns.
GO15 members will need to be proactive in the integration design of this new technology and be advocates for common positions of the Power Grid Operators. The goal of WG #6 is to evaluate the impacts of PEVs on the planning, operation and markets of the electric power systems as well as jointly address the common set of challenges and opportunities that each of the represented countries will experience as a result of PEV acceptance and deployment.
