This article focuses on the optimization of energy management strategy (EMS) for the tram equipped with on-board battery-supercapacitor hybrid energy storage system. The purposes of the optimization are to prolong the battery life, improve the system efficiency, and realize real-time control. Therefore, based on the analysis of a large number of
Braking energy of trams can be recovered in storage systems. • High power lithium batteries and supercapacitors have been considered. • Storage systems can be installed on-board or along the supply network. • A
The operation interval is S9 – S10. The energy-saving effects of the three methods are apparent, and the BM-PSO model performs best. (3) Under the ideal working condition, the total energy consumption of the GA, classical PSO, and BM-PSO methods are 35.13 kWh, 34.99 kWh, and 34.32 kWh.
1. Introduction There is a growing interest in ''green'' energy, prompted by both government regulations, and general interest amongst the population in achieving a low carbon future through the adoption of cleaner transportation (Rezvani et al., 2015, Brady and O''Mahony, 2011).).
With the development of the photovoltaic industry, the use of solar energy to generate low-cost electricity is gradually being realized. However, electricity prices in the power grid fluctuate throughout the day. Therefore, it is necessary to integrate photovoltaic and energy storage systems as a valuable supplement for bus charging stations, which

Compared with traditional tram powered by a DC catenary, energy efficiency of the catenary-free tram can be enhanced considerably due to increased recuperation of braking energy [4], [5]. For traditional tramlines, the regenerative energy of the trams is not stored, but rather immediately delivered to adjacent trams that are in an
SCs are mainly devoted on supplying fast peak loads produced by the tramway during acceleration, while the battery energy storage (BES) system provides large storage capacity [23]. In both cases, DC-DC converters are installed to properly operate the storage devices as well as keep catenary voltage constant [20] .
