Combined with the operation condition of the tram, the optimal sizing model of hybrid energy storage system is established. An improved PSO algorithm with competition mechanism is developed for obtaining the optimal energy storage elements.
Typically, storage systems for tramway installations encompass batteries and super-capacitors (SCs) , , . Stationary battery energy storage (BES) systems compared to other technologies improves traction efficiency and reduces associated costs, reaching savings rate of up to 25% , , .
The modern tram system is an essential part of urban public transportation, and it has been developed considerably worldwide in recent years. With the advantages of safety, low cost, and friendliness to the urban landscape, energy storage trams have gradually become an important method to relieve the pressure of public transportation.
The new technology is based on an onboard energy storage system (OBESS), with scalable battery capacity. It can be installed directly on the roof of existing trams - saving on costs, and visual impact – all while ensuring better environmental performance for a more sustainable society. In Florence, battery powered trams have been tested since 2021.
Compared with the traditional overhead contact grid or third-rail power supply, energy storage trams equipped with lithium batteries have been developed rapidly because of their advantages of flexible railway laying and high regenerative braking energy utilization.
As the sole power source of the tram, the battery pack can supply power to the traction system and absorb the regenerative braking energy during electric braking to recharge the energy storage system. The traction system mainly consists of the inverter, traction motor, gearbox, and axle.
As tram utilization increases, the operational energy consumption of the tram system grows. Therefore, it is crucial to save energy and reduce the energy consumption of trams. One promising approach is to optimize the speed trajectory of the tram, also known as energy-efficient driving [1, 2].
Combined with the operation condition of the tram, the optimal sizing model of hybrid energy storage system is established. An improved PSO algorithm with competition mechanism is developed for obtaining the optimal energy storage elements.
