Abstract. Advanced Rail Energy Storage (ARES) has developed a breakthrough gravity-based technology that will permit the global electric grid to move effectively, reliably, and cleanly assimilate renewable energy and provide significant stability to the grid. ARES stores energy by raising the elevation of mass against the force of
Grey wolf optimization technique with embedded CPLEX solver is utilized to solve this RTSEM problem. The proposed model is tested with a real high-speed railway line
We have estimated the ability of rail-based mobile energy storage (RMES) — mobile containerized batteries, transported by rail between US power-sector regions 3
Total energy demand for the rail sector in 2050 is around 42% more than in the Base Scenario. Yet despite increases in activity, rail transport still accounts for only 4% of total transport energy demand in 2050. In both of the scenarios the rail sector experiences strong electrification, and therefore energy diversification.
The integration of hybrid energy storage systems (HESS) in alternating current (AC) electrified railway systems is attracting widespread interest. However, little attention has been paid to the interaction of optimal size and daily dispatch of HESS within the entire project period. Therefore, a novel bi-level model of railway traction substation
Modelling the use of energy storage units in railway application needs to accurately reproduce in terms of energy and power

Huang et al. [14] synthetically tuned speed profiles and running times over each inter-station sector with on-board energy storage devices to maximize the use of regenerative energy.
Traction power fluctuations have economic and environmental effects on high-speed railway system (HSRS). The combination of energy storage system (ESS)
The aim is to study the potential for energy and economic savings of the railway operation as well as energy storage systems behavior. A real case study is analyzed for a Spanish high-speed
The large ("grid scale") ARES projects could range from 200 MW to 3 GW, which is a hell of a lot of storage — enough, the company says, to provide four to 16 hours of power at full output.At
Finally, a simulation analysis with actual load of a high-speed railway station is performed. The highest benefit is achieved when the regenerative braking energy is partially recovered by the HESS, which can save 3% of the total cost per day and pay back the cost in eight years.
Reduction of energy consumption has become a global concern, and the EU is committed to reducing its overall emissions to at least 20% below 1990 levels by 2020. In the transport sector, measures are focused on planning, infrastructure, modal change, the renewal of vehicles and also programmes for efficient driving. Factors such as the low
As for the master level model, comprehensive cost study within the project period is conducted, with batteries degradation and replacement cost taken into account. Grey wolf optimization technique with embedded CPLEX solver is utilized to solve this RTSEM problem. The proposed model is tested with a real high-speed railway line case in China.
The Matlab based model has been experimentally validated considering an Italian high-speed test case: the ETR 1000 high-speed train fed by the 3 kV DC feeding system, from Florence to Rome. i.e. regenerative braking and energy storage, within a DC high-speed railway system. Two different DC railway models have been developed
Regenerative braking energy requires energy storage systems with both high power density and high energy density to recycle it. This paper uses HESS combined with supercapacitors and batteries to
This paper proposes an energy storage system (ESS) of the high-speed railway (HSR) for energy-saving by recycling the re-generative braking energy. In this case, a supercapacitor-based storage
