Reducing Power Peaks and Energy Consumption in Rail Transit Systems by Simultaneous Train Running Time Control

This paper presents a new approach to train running time control in order to achieve energy cost reductions. Given an optimal combination of headways and synchronization time, it is sufficient to apply a controller based on the minimization of a single train's energy using dynamic Programming. When these conditions can not be met, the modification of train running times can contribute to significantly reducing power peaks and energy consumption and thereby reducing energy costs in rail transit systems.
