Design and control of resilient interconnected microgrid for sustained railway

Abstract

This paper demonstrates the design and control of a resilient interconnected microgrid to support railway infrastructure. A microgrid can alleviate some of the issues due to their proximity to local power substations. When coupled with a transportation network, the microgrid can become useful in supporting the transportation network during regular operation, and emergency events. A grid-connected microgrid will be formed using a photovoltaic system, wind turbine, battery bank and flywheel energy storage system. The microgrid will also be able to take advantage of the recovered energy from the train when it is braking. A microgrid supervisory controller will be used to balance the energy steams exchanged between the train and microgrid. The proposed solution has been demonstrated using simulation and real data, where the achieved results confirm the effectiveness of the proposed control architecture in terms of cost, performance and resilience.
