Simulation results demonstrate lithium-ion batteries offer optimal efficiency in electric traction systems under cost constraints.
This paper presents the results of a study on the use of energy storage systems in electric traction systems, conducted using the Matlab Simulink software environment. The relevance of implementing energy storage systems lies in the current inability to fully utilize regenerated energy during braking. The analysis of available types of electrical energy storage devices reveals that several variants exist, each requiring specific charging parameters. By applying an analytical approach to modeling electric traction loads, various scenarios of integrating storage devices into subway power supply systems were examined. The simulation results demonstrate that, under cost constraints for the storage system, lithium-ion batteries provide the highest efficiency among the considered technologies.
