The objective of this paper involves the analysis and the study of opportunities for the management of Railway Power Systems demand through some models and tools well known in Public Power Systems: Physically Based Load Models and Distributed Energy Resources (load management, on-board generation and energy storage). The paper considers exciting trends for the development of railway transportation driven by energy policy scenarios and the developments of modern and refurbished power units (e.g. last-mile capacity). Moreover, the management of Railway Power System can support the necessary flexibility of the main Power System to enhance the flexibility of the system while improving the integration of renewable. The paper is focused on the use of two possibilities: the control of HVAC loads in trains and the use of on-board generation of trains with last mile capacity to manage the demand and, in this way, face to the problem of synchronized timetables which causes high power peaks in railways. Results justifies the opportunity to develop flexibility of railway units, which improves the social and economic of railway transportation.
