The electric transportation systems as huge demands of main electric network, play major role in transferring passengers and goods throughout the world. Since the peak power consumption of mentioned systems, have time overlap with the peak power demand of main electric network, the supplying procedure of them has negative impacts on their upstream grid. One of the best solutions to alleviate the negative impacts is the utilization of regenerated energy of braking trains as a distributed generation in electric transportation system as well as the solar energy sources in other power systems. The distributed generations will penetrate into the supply chains more effectively if benefit from energy storage systems. The scope of this study is shaving the peak power consumption of electric transportation system by proposing an integrated electric transportation system containing electric railway system, fast charging station for electric vehicles, energy storages and distributed generations. A smart energy management system defines power flow strategies so that the shifting power demand from grid point of view could be proceeded. To clarify the issue, the smart configuration is compared with the traditional system. Thus, the proposed configuration is simulated in HOMER software and results are analyzed.
