An Estimation of the Energy Savings of a Mainline Diesel

In existing studies, two approaches to the use of energy storage devices are proposed [9–11]. The first is that the energy storage is integrated into the diesel gen-erator set, and they can work on a common load [12–14]. The second involves energy storage that is placed on a separate section and interacts only with the traction drive of this

Energy management strategy to optimise regenerative

Embedded energy storage sources such as SCs or batteries are used to perform recovery braking. They are a more viable alternative to recover energy during braking. This option is similar to the one used in an application with a high-start/stop frequency such as elevators driven by synchronous machines [36, 37].

Energy storage devices in electrified railway systems: A review

2.6 Hybrid energy-storage systems. The key idea of a hybrid energy-storage system (HESS) is that heterogeneous ESSes have complementary characteristics, especially in terms of the power density and the energy density . The hybridization synergizes the strengths of each ESS to provide better performance rather than using a single type of ESS.
