Abstract

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