Adapting Digital Twin Technology in Electric Railway Power Systems

Electric Railway as a high-power load system in power grids known as a key technology in transportation industry. Due to the complexity and breadth of such networks, executing an exact simulation as an integral part of this technology plays a crucial role to obtain reliable and secure operations based on the performance of real physical system. In this context, implementation of Digital Twin (DT) can ensure the correct operation of monitoring and control function. In this paper, an approach is presented to implement DT concept both at equipment and system level of Electric Railway Power Systems (ERPSs). It has been shown that DT capabilities to describe the actual and probable future state-run, makes it an unavoidable resolution for ERPS.
