Abstract :
This paper evaluates the cost effectiveness of using regenerative braking in a tram line in case of non-reversible substations equipped with battery energy storage. It shows, by the combination of results by numerical simulation model and experimental tests, how it is possible to effectively transform an existing tramway to improve its energy efficiency. Results have shown that also from the economical point of view the proposed solution can be of great interest for the transport company wishful to update its system technology.
