Reduced-scale power hardware-in-the-loop simulation of a hybrid railway power substation

With the growth of the passenger flow in railway transportation system in France, some railway substations are
approaching their power limits, thus have difficulty to reinforce the power supply. The substation upgrade
usually requires changing power transformers and connecting cables, thus costly. The integration of renewable
energies and storage system to form a hybrid railway power substation (HRPS) could be a good solution, which
can satisfy the power requirement with smaller investment, and also opens an opportunity to participate into the
electricity market. Instead of build the prototype directly, this paper proposes a reduced-scale power hardwarein-
the-loop (HIL) simulation platform to verify the technical availability of HRPS.
