Energy storage systems (ESSs) play a significant role in performance improvement of future electric traction systems. This paper investigates an ESS based on supercapacitors for trams as a reliable technical solution with considerable energy saving potential. Operating the ESS onboard a tram brings the following benefits: reduction of peak power demands, decrease of power consumption, improvement...
The paper is concerned with the comparison of four basic control strategies of the on-board energy storage system. The energy storage system is able to increase the tram efficiency and decrease operating costs. The comparing criteria are energy savings of strategies. Energy savings are calculated via stochastic model of the real tram line. Return on the investment is also estimated in this paper.
