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% , , .
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.
Wang et al. comprehensively considered the characteristics of the tram HESS, line conditions, and traction characteristics, took the mass of the supercapacitor as the optimization goal, optimized the parameters, and extended the battery life while reducing the mass of the ESS.
However, trams may face expensive battery replacement costs due to battery degradation. Therefore, this paper proposes a multi-objective optimization method for the tram's driving strategy to reduce operational energy consumption and extend battery life. The method describes the optimization problem as second-order cone programming (SOCP).
Battery-powered tramways are a type of public transportation system that rely on batteries for power. New projects in this field often focus on lithium-ion (Li-ion) batteries, which is a family of electrochemistries that has developed over the last 30 years. One relatively new type of Li-ion battery is Lithium Titanate Oxide (LTO).
The greater the distance between stations, the greater the demand energy. The first interval has the largest distance and maximum energy consumption. If the recovered braking energy is not included, the energy consumption is 7.012 kwh. Fig. 3. DC bus demand energy curve. The tram adopts the power supply mode of catenary free and on-board SESS.
