The growing interest in the use of energy storage systems to improve the performance of tramways has prompted the development of control techniques and optimal storage devices,
Electronics 2020, 9, 129 2 of 19 period. Li-ion batteries have a low power density and slow charging/discharging rates, e.g., taking several hours for charging. The supercapacitors have
PV panels, a DC/DC converter, and a (battery/supercapacitor) storage system are all components of the system under study (Figure 1). Long-term energy storage is possible with battery technology. Supercapacitors can
These systems will be presented and discussed in future sections. Also, the hybrid energy storage systems (HESS) such as PV–battery supercapacitors or fuel cells are proposed as a different
