A Study on the Virtual Operation of Energy Storage Devices using the Electric Railway System HILS Platform

Eco-friendly issues are demanding changes in the transportation fields, including the railway system. Accordingly, the Electric Railway System(ERS) is conducting a lot of research on energy storage devices to recycle and improve the efficiency of regenerative energy. However, field tests to confirm the system applicability and performance of such electrical facilities are accompanied by risks such as human accidents due to high-voltage tests and disruption of commercial operation of trains. Accordingly, this paper proposes a virtual operation technology that can replace low-efficiency field tests through safe and efficient performance evaluation of electrical facilities using the lab-scale Hardware In the Loop Simulation(HILS) platform with real time simulation.
