Scheduling Charging of Electric Vehicles for Optimal Distribution Systems Planning and Operation

Paper in proceedings, 2011

In the not so distant future, it is expected a large-scale integration of fleets of plug-in electric vehicles (PEVs) in the transport sector. Such large number of PEVs will increase the demand of electrical energy and as a consequence the losses in the electric distribution grid will increase. Equally there might be a need to reinforce the grid to be able to adequately supply the increased load. This paper presents a model to schedule the charging of PEVs while minimizing the grid losses. The model can also determine the maximum number of vehicles that can be handled by the grid without any need for reinforcement. The result shows that the losses can be reduced with up to 6% as compared to those of the uncontrolled charging and the number of vehicle that can be handled by the grid increases substantially.
