“…The brake is considered as a current source that imposes the current i bk (1). Finally, the resistance R f represents the losses in the input filter [23–25]. The EMR of the train will be described in the following sections because it depends on the implementation of the DC bus and braking subsystem models.…”

“…The first simulation approach is based on a DM of the train DC bus (see Fig. 6) [23–25]. The respect of the integral causality leads to represent the train (from the point of view of the DCTN) as a voltage source u f with a series resistance R f .…”

“…Again, the train model will read first the power reference provided by the external software (P train mech,re f ). To obtain the train electrical reference power (P train re f ), the mechanical power will be multiplied by the efficiency of the electromechanical conversion (see Equation (8)). This efficiency will be labeled as the train efficiency in braking mode (ν train b ).…”

“…For instance, in [7], the authors compared different traction substation models. The models presented using the EMR were extremely accurate and precise [8], and they may describe every single part of the system and are appropriate for applications in which the transient behavior of the trains is critical, such as hardware in the loop applications [9]. A very detailed model of an electric train fed by supercapacitors connected to fuel cells was presented in [10].…”

In this paper, a decoupled model of a train including an on-board hybrid accumulation system is presented to be used in DC traction networks. The train and the accumulation system behavior are modeled separately, and the results are then combined in order to study the effect of the whole system on the traction electrical network. The model is designed specifically to be used with power flow solvers for planning purposes. The validation has been carried out comparing the results with other methods previously developed and also with experimental measurements. A detailed description of the power flow solver is beyond the scope of this work, but it must be remarked that the model must by used with a solver able to cope with the non-linear and non-smooth characteristics of the model. In this specific case, a modified current injection-based power flow solver has been used. The solver is able to incorporate also non-reversible substations, which are the most common devices used currently for feeding DC systems. The effect of the on-board accumulation systems on the network efficiency will be analyzed using different real scenarios.

“…This is an important issue because electromechanical limitations can have a major impact on the kinematical behavior of the model (e.g., the variation in traction and braking curves, due to voltage values on overhead lines, which affects accelerations and changes timetables). The interest and impacts of this feedback is analyzed in the literature [66]. In the case of diesel units, they also have dynamic braking, in which the power supplied by motors are used to feed roof resistors cooled with forced ventilation.…”

The objective of this paper involves the analysis, identification and evaluation of different possibilities offered by technology for the improvement and the management of the use of energy and hybridization in railways: On board generation, demand response and energy storage, both in traction and auxiliary loads, considering the aggregation of resources and its stochastic nature. The paper takes into account the importance of efficient use of energy in railways, both currently (trains in service, prototypes) and in the future, considering the trends driven by energy policy scenarios (2030–2050) that will affect service and operation of units during their lifetime. A new activity has been considered that will be relevant in the future in the framework of a new electricity supply paradigm: Smart-Grids. According to this paradigm, the interaction of the Electric Power System and the Railway Supply System (somehow embedded in the Power System) will bring new opportunities for the collaboration of these two systems to perform, in a wise economic fashion, a better and more reliable operation of the complete energy system. The paper is focused on a mixed profile with low-medium traffic (passenger and freight): The first part of the route is electrified (3 kV DC catenary) whereas the second part is not electrified. Results justify that complex policies and objectives bring an opportunity to make cost-effective the hybridization of railway units, especially in low/medium traffic lines, which improves their social and economic sustainability.
