“…The performance of HESS is always better compared to a single ESS. However, HEESs also have some drawbacks such as having a complex control strategy as two or more different ESSs are used thus increased in maintenance and cost are inevitable, [139]- [141].…”

<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>

This study presents a control system to track the sinusoidal ripple current (SRC) of lithium (Li)-ion batteries. In this method, a combination of a DC and a sinusoidal ripple current is injected to the battery. By choosing the appropriate frequency, the minimum AC impedance of the battery is obtained. This study, the impact of temperature has been considered as a protection criterion in the proposed charge algorithm, also a state-space model of the charger system has been developed, and finally a pole placement controller has been proposed to control charging current. To evaluate the design, a laboratory setup has been implemented to obtain experimental results from a 1 kW Li-ion battery pack. Also, simulations have been carried out by Simulink/MATLAB. The proposed pole placement control method for tracking of SRC and the optimal frequency detection algorithm have been designed and tested on a practical 10 Ah Li iron phosphate battery pack in different charge modes. In addition, results of the conventional proportional-integrator (PI) controller have been compared with the proposed controller. Both simulation and experimental results show the effectiveness of the proposed algorithm and control system to track SRC reference current in all frequencies.

“…To avoid braking energy feedback to the public power grid, the current technical solutions are: energy storage [7,[10][11][12], inverter feedback [10][11][12], and inverter load [12]. Because coal-laden trains are heavy-haul trains, which are powerful and have a long running time, regenerative braking energy needs to be recovered by energy storage devices with high energy density and large volume.…”

“…The feedback of energy back to the railway company is of the low-voltage power grid inverter feedback type, which requires the installation of a converter to ensure the stability of the load electricity. Moreover, there is typically a long distance between trains and railway companies, and the transmission costs are high [11]. Electricity fed back to the pantograph is used by trains or other loads operating in the reverse direction within the same supply interval, known as the inverter load solution, which is a less expensive and more efficient means of utilization.…”

AC heavy-haul trains produce a huge amount of regenerative braking energy when they run on long downhill sections. If this energy can be used by uphill trains in the same power supply section, a reduction in coal transportation cost and an improvement in power quality would result. To accurately predict the energy consumption and regenerative braking energy of heavy-haul trains on large long slopes, a single-particle model of train dynamics was used. According to the theory of railway longitudinal section simplification, the energy consumption and the regenerative braking energy model of a single train based on the train attributes, line conditions, and running speed was established. The model was applied and verified on the Shenshuo Railway. The results indicate that the percentage error of the proposed model is generally less than 10%. The model is a convenient and simple research alternative, with strong engineering feasibility. Based on this foundation, a model of train energy consumption was established under different interval lengths by considering the situation of regenerative braking energy in the multi-train operation mode. The model provides a theoretical foundation for future train diagram layout work with the goal of reducing the total train energy consumption.
