This paper presents an analysis on using an on-board energy storage device (ESD) for enhancing braking energy re-use in electrified railway transportation. A simulation model was developed in the programming language C++ to help with the sizing of the ESD. The simulation model based on the mathematical description has been proposed for a train equipped with on-board ESD for analysis of effectiveness of its application. A case study was carried out for a metro line taking into consideration train characteristics, track alignment, line velocity limits and a running time table. This case study was used to assess the energy savings and perform a cost-benefit analysis for different sizes of the on-board ESD by applying the proposed approach. It was shown that when additional environmental benefits (reduction of CO2 emissions) are considered, this may significantly improve effectiveness of the investments due to CO2 European Emission allowances.

“…Since the AC network is permanently receptive, there is the possibility of full braking energy recovery, excepting the inherent losses in transporting this energy back to the grid. Although there are many papers on the topic of reversible substations focused on different implementations, such as [44][45][46][47][48][49], there are few topical synthesis papers. A very recent review on the methods used for regenerative braking energy recovery, including the reversible substations, is presented by Khodaparastan in [50].…”

This study is focused on the topical issue of increasing the energy efficiency in DC railway systems, in the context of global concerns for reducing the CO2 emissions by minimizing the energy consumption and energy loss. The main achievements in this complex issue are synthesized and discussed in a comprehensive review, emphasizing the implementation and application of the existing solutions on concrete case studies. Thus, all specific subtopics related to the energy efficiency are covered, starting with power quality conditioning and continuing with the recovery of braking energy, of which a large part is lost in the classic DC-traction substations. The solutions of onboard and wayside storage systems for the braking energy are discussed and compared, and practical examples are given. Then, the achievements in transforming the existing DC-traction substations in reversible substations with capabilities of power quality improvement are systematically reviewed by illustrating the main results of recent research on this topic. They include the equipment available on the market and solutions validated through implementations on experimental models. Through the results of this extensive review, useful reference and support are provided for the research and development focused on energy efficient traction systems.

“…Although inverters have been used in traction power supply system (TPSS) for several years, few literature discusses the optimization of the operating characteristics for regenerative inverters. The most commonly used operating characteristics of the inverter used in railway substation is constant voltage control [27][28][29]. It is easy to implement and beneficial for the stabilization of DC network voltage.…”

“…Two possible inverter control schemes: the constant advance angle control and the constant voltage control were illustrated in [3,4], but the impact of operating characteristics on the energy saving and energy distribution were not studied. In addition, the capacity configuration of inverters in TPSS usually depends on system simulation [27,28], but in most existing simulation systems, an inverter is simply modeled as an ideal voltage source or a voltage source with internal resistance. The power limitation of the inverter is not considered in the inverter model.…”
