Flexible electric vehicle (EV) charging to meet renewable portfolio standard (RPS) mandates and minimize green house Gas emissions

摘要

Meeting RPS mandates and accommodating EVs poses a difficult problem for utilities. This paper proposes coupling EV charging with the availability of renewable energy at the point of use to realize dramatic system level benefits. A realistic set of scenarios are simulated, using real-time grid data from NYISO and wind farm data from NREL, to prove that with a small percentage of wind energy penetration and flexible EV charging, GHG emissions of the light-duty transportation sector can be dramatically reduced. This is achieved without any additional generation requirements from the existing power grid, while providing the additional benefit of reducing the spinning reserve requirements needed to cope with the intermittency problem of the new wind resource. The concept of a parallel market structure as a means to practically implement the concepts in this paper is also introduced.
