Type of on-board energy storage device

Can onboard energy storage devices reduce the catenary energy consumption?

Abstract: For improving the energy efficiency of railway systems, onboard energy storage devices (OESDs) have been applied to assist the traction and recover the regenerative energy. This article aims to address the optimal sizing problem of OESDs to minimize the catenary energy consumption for practical train operations.

What are on-board energy storage devices (hesds)?

As an emerging technology, on-board HESDs are usually composed of different types of energy storage devices, namely, batteries (BATs), supercapacitors (SCs), and flywheels, where the hybridization solutions to BATs and SCs are widely applied in electric vehicles and rail transportation [ 5, 6 ].

What are some alternative solutions to onboard energy storage?

Innovative paradigms for the supply system, such as inductive power transfer technology, will unfold alternative solutions to onboard energy storage for long-range wireless operation of rail vehicles. Smart energy management strategies will thus be required for reliable and energy-efficient operation of the railway system.
