Modeling and Simulation of DC Electric Rail Transit Systems With Wayside Energy Storage.

Electric rail transit systems are large consumers of electricity, which face challenges related to improving their overall energy efficiency. Although various solutions have been proposed to achieve this target, it is not feasible to implement and test all of them. Since finding the solution that is most appropriate to a given system is typically a site-specific problem, an accurate, validated, and reliable simulation tool is crucial. In this paper, a simulation model for studying wayside energy storage systems in dc electric rail transit system is presented. The proposed model provides a reliable tool for analyzing the behavior of the transit system during intervals that span from a small fraction of time (milliseconds) up to 24 h. In order to validate the proposed simulation model, its results were compared with real measurements of a standard subway system. [ABSTRACT FROM AUTHOR]
