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.
