  This paper proposes a novel optimal Energy Management System (EMS) algorithm
for Electric Vehicle (EV) charging in smart electric railway stations with
renewable generation. As opposed to previous railway EMS methods, the proposed
EMS coordinates the combined Regenerative Braking Energy (RBE), renewable
generation, electric railway demand and EV charging demand at the EV parking
lot of the railway station. Numerical results using a scenario-based approach
on an actual railway station in Chur, Switzerland demonstrate that the proposed
algorithm can effectively minimize the expected daily operating cost for the
train station over an entire year.
