Energy storage systems (ESSs) are the technologies that have driven our society to an extent where the management of the electrical network is easily feasible. The balance in supply-demand, stability, voltage and frequency lag control, and improvement in power quality are the significant attributes that fascinate the world toward the ESS technology. However, being one of the oldest ESS, the flywheel ESS (FESS) has acquired the tendency to raise itself among others being eco-friendly and storing energy up to megajoule (MJ). Along with these, FESS also surpasses the quality of high power density, longer life cycle, higher rate of charge and discharge cycle, and greater efficiency. In this article, an overview of the FESS has been discussed concerning its background theory, structure with its associated components, characteristics, applications, cost model, control approach, stability

“…The substations are modeled as reversible devices, but reverse power flows (from DC traction systems to the AC network) are avoided through the use of a wayside energy storage devices. More examples of static simulators of DC traction networks with wayside energy storage can be observed in [18], [46]. In both cases, a mathematical model is proposed and implemented to study a specific scenario and evaluate the potential regenerative energy, voltage stabilization and reduction of peak power demand that can be obtained with this technology.…”

“…As it can be observed, [1] is probably the most similar work when compared to the present paper, but in this case the paper is focused on describing power electronic technologies added to the power supply systems and it is only focused on describing the technologies but not the mathematical models and the simulation methods presenting such technologies. Something similar could be stated about reference [17] focused only in power electronic converters embedded in AC railway power supply systems and reference [18] just focused on wayside energy storage systems and their impact over the power supply network. Reference [19] is focused on describing power quality issues present in power supply systems and the work presented in [20] studies the substitution of conventional power transformers by power electronic transformers but mainly for rolling stock applications and not for power supply ones.…”

A review of railway feeding infrastructures: Mathematical models for planning and operation

et al. 2020

View full text Add to dashboard Cite

In this paper, the authors review the mathematical models, simulation and analysis techniques and energy management systems proposed for railway power supply systems. The authors review both AC and DC railway feeding systems making special emphasis in those that consider new technologies like on-board or wayside energy storage, integration of renewable energies in the traction networks or the use of power electronic devices to increase the efficiency and controllability of the networks. The paper is divided in two main blocks studying DC and AC systems. In both parts, a review of the main simulation tools and models is presented but also a detailed list of specific cases of use of such techniques.

“…Many modern railway systems are equipped with bidirectional substations that have the ability to capture the recuperated braking energy from a decelerated train through the third rail or overhead catenary [9]. Then, instead of dissipating it in the vehicle brake resistors, the recovered energy can be fed back into the other nearby accelerating trains or can be stored in the stationary energy storage (ESs) for the later use.…”

Providing uninterrupted electricity service aboard the urban trains is of vital importance not only for reliable signaling and accurate traffic management but also for ensuring the safety of passengers and supplying emergency equipment such as lighting and signage systems. Hence, to alleviate power shortages caused by power transmission failures while the uninterruptible power supplies installed in the railway stations are not available, this paper suggests an innovative traction drive topology which is equipped by an onboard hybrid energy storage system for railway vehicles. Besides, to limit currents magnitudes and voltages variations of the feeder during train acceleration and to recuperate braking energy during train deceleration, an energy management strategy is presented. Moreover, a new optimal model predictive method is developed to control the currents of converters and storages as well as the speeds of the two open-end-windings permanent-magnet-synchronous-machines in the intended modular drive, under their constraints. Although to improve control dynamic performance, the control laws are designed as a set of piecewise affine functions from the control signals based on an offline procedure, the controller can still withstand real-time non-measurable disturbances. The effectiveness of proposed multifunctional propulsion topology and the feasibility of the designed controller are demonstrated by simulation and experimental results.
