Abstract
The paper reports a technical-economic comparison for a Turkey high-speed railway line, between 25 kV AC electrification and the use of hybrid trains with on-board storage systems. On-board battery storage systems have been designed to operating in specific parts of the line. Different types of technologies have been taken into account, evaluating the use of high specific power/energy lithium-ion electrochemical cells. The models of the battery pack have been designed in the MATLAB/Simulink environment, in order to carry out the complete operation check, also evaluating the time and power required for recharging. An economic evaluation and comparison have been carried out in order to evaluate the convenience of using a hybrid train on specific part of a real line in order to not totally electrified the line.
