  In this paper, an electric railway Energy Management System (EMS) with
integration of an Energy Storage System (ESS), Regenerative Braking Energy
(RBE), and renewable generation is proposed to minimize the daily operating
costs of the railway station while meeting railway and Electric Vehicle (EV)
charging demand. Compared to other railway EMS methods, the proposed approach
integrates an optimal EV charging policy at the railway station to avoid high
power demand due to charging requirements. Specifically, receding horizon
control is leveraged to minimize the daily peak power spent on EV charging. The
numerical study on an actual railway station in Chur, Switzerland shows that
the proposed method that integrates railway demand and optimal EV charging
along with ESS, RBE, and renewable generation can significantly reduce the
average daily operating cost of the railway station over a large number of
different scenarios while ensuring that peak load capacity limits are
respected.
