Should rail vehicles have onboard energy storage systems?

However, the last decade saw an increasing interest in rail vehicles with onboard energy storage systems (OESSs) for improved energy efficiency and potential catenary-free operation. These vehicles can minimize costs by reducing maintenance and installation requirements of the electrified infrastructure.

Can resonant power transmission be used as a long-range energy storage solution?

On the other hand, 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. Magnetic resonant power transmission has already been tested on scales of hundreds of metres with promising results.

Can energy storage be used in electrified railway?

Many researchers in the world have put a lot of attention on the application of energy storage in railway and achieved fruitful results. According to the latest research progress of energy storage connected to electrified railway, this paper will start with the key issues of energy storage medium selection.

What is ground energy storage access scheme of electrified railway?

Table V. Ground energy storage access scheme of electrified railway. Its voltage level is high, which can reduce the loss caused by energy transmission in the line to a certain extent, and the capacity of ESS is large. It has a low voltage level and is only suitable for short-distance transmission to supply power to station loads.

What are the control strategies of energy storage device?

Control strategy of energy storage device Energy storage device is composed of energy storage medium and bidirectional DC/DC converter. The control strategies of energy storage device include constant current control, constant power control and voltage/current double closed loop control .

What is energy storage converter?

The energy storage converter can provide reactive power regulation, and the energy storage device itself can perform active power regulation. Making full use of the ESS to comprehensively manage the power quality can significantly reduce the repeated investment. 4.1. Three phase unbalance
