Their primary efforts aim to reduce traction energy demand, replace diesel, and limit the impact of electrified overhead infrastructures. From a system-level perspective, the integration of alternative energy sources on board rail vehicles has become a popular solution among rolling stock manufacturers. The tram has a hybrid storage system
energy consumption was a subject of interest for design ing energy storage. First, the tram characteristics data was collected. The surveyed tram routes had many operating parameters e.g. time per cycle, number of passengers, and travel distance, etc. Collected data was simulated in order to generate the driving cycle pattern.
The more commonly used is on-board energy storage technology. There are some similarities between a tram with on-board energy storage and an electric vehicle.
Hybrid electric trams equip with additional on-board energy storage devices to improve the performance of power sources. Both of optimal energy management and velocity control are important to maximum the energy efficiency for catenary-supercapacitors hybrid trams. An optimal control model has been developed to minimize energy consumption from traction
