As adoption of Plug-in Electric Vehicles (PEVs), grows, the power drawn by charging loads may create localized problems for distribution networks, including overloads, voltage profile degradation, and unbalance. At the macro grid level, uncoordinated charging of large populations ofPEVs could exacerbate peak loads. Development of advanced control strategies and protocols is needed to coordinate PEV charging and develop interfaces for accelerating the deployment of PEV s.
