“…A good method of improving the energy efficiency (by 8%) is the effective use of regenerative energy by dwell time optimization in urban rail transit using genetic algorithm [9], based on the traffic schedule of traction vehicles. It is also expected that the implementation of an on-board (OBESS) and a way-side (WESS) [10] or a track-side (TESS) [11] energy storage system could have a large impact on instantaneous as well as on demanded power reduction.…”

“…In the case of the OBESS structure, electric double-layer capacitors (EDLC) [11] are increasingly used. According to [5] the implementation of an OBESS with the peak demand reduction strategy may support reduction of the peak power by 63.49% and energy saving by 15.56% in a DC traction substation.…”

“…A good and proven solution is also the implementation of flywheel energy storage (FES) [12]. On the other hand the use of some battery technologies, for example, nickel metal hydride (NiMH) technology, may be associated with a potential risk of cell explosion [11]. Although the implementation of a WESS [13] or TESS based on supercapacitor (SC) technology also has a positive effect on the peak power reduction [13], and the off-board location allows for a freer use of a wider group of energy storage (ES) technologies, especially lithium-ion (Li-ion) [14].…”

This paper introduces the concept of fault-tolerant control (FTC) of a multi-string battery energy storage system (BESS) in the dynamic reduction system of a traction substation load (DROPT). The major task of such a system is to reduce the maximum demand for contracted peak power, averaged for 15 min. The proposed concept, based on a multi-task control algorithm, takes into account: a three-threshold power limitation of the traction substation, two-level reduction of available power of a BESS and a multi-string structure of a BESS. It ensures the continuity of the maximum peak power demand at the contracted level even in the case of damage or disconnection of at least one chain of cells of the battery energy storage (BES) or at least one converter of the power conversion system (PCS). The proposed control strategy has been tested in a model of the system for dynamic reduction of traction substation load with a rated power of 5.5 MW. Two different BESS implementations have been proposed and several possible cases of failure of operations have been investigated. The simulation results have shown that the implementation of a multi-string BESS and an appropriate control algorithm (FTC) may allow for maintenance of the major assumption of DROPT, which is demanded power reduction (from 3.1 MW to 0.75 MW), even with a reduction of the BESS available power by at least 25% and more in the even in fault cases.

“…With this solution, the total energy consumption required by the vehicle from the substation during the acceleration process is greatly reduced. The benefits of using energy storage systems in storing the regenerated energy are not only for total energy consumption reduction but also for providing reduction in peak power and demand, catenary-line voltage stabilization, compensation of power and energy, and enables the vehicles to have autonomous driving (called catenary-free driving) where a vehicle can continue to run freely without having to connect to the catenary line for power supply [14], [47], [48].…”

<p>Electrified urban railway systems are large consumers of energy in urban areas and thus, there is a need for energy saving measures in this transportation sector. Recuperation of train’s regenerative braking energy (RBE) is one of the best ways for attaining high levels of energy efficiency in this area. Energy Storage Systems (ESSs) prove to be the most practical and viable solution for maximizing the RBE utilization in urban railway systems. In the existing related reviews of ESSs, few papers covered the review of ESS technologies or converter interface. However, a comprehensive review is needed in this regard. This paper discusses an overview of urban railway electrification, and detail review for the three ESS components – ESS Technologies, Bidirectional DC-DC Converters (BDCs), and Controller Unit. This study concludes that among the storage technologies, supercapacitor ESS appears to be the most suitable followed by Lithium-ion batteries and flywheels. For BDC, cascaded BDC is the most suitable followed by dual active bridge. For control methods, fuzzy logic and artificial intelligent are recommended among other control strategies. Thus, the key contribution of this paper is the comprehensive review and analyses of the ESS’s components in the recovery of RBE in urban railways. </p>
