Techno-Economic Optimization of Railway Power Substation Hybridization

With the rising of railway traffic flow, railway system suffers problems like voltage drop, unbalance, etc. One
promising solution, studied in this paper, is the hybridization of railway power substation. The design of this
hybrid architecture is complex and depends on a lot of techno-economic parameters. This paper develops technoeconomic
models used for optimization that takes into account all Life Cycle Cost. An example of AC power
substation is studied and results reveal that the return of investment (ROI) period is around 4 years with the
integration of energy storage system and wind power system.
