Applicability and development of a direct method algorithm for simultaneous optimization of trajectories and energy minimizing control for hybrid fuel cell railway vehicles

Abstract

The content of this paper presents a method to determine an energy-optimal operation of a battery-electric fuel cell hybrid train. As a novelty in the realms of numerical energy optimization is the simultaneously optimization of the actual energy management and train operation. To assess on the hydrogen savings potential made available by the developed optimization method, a comparison against a rule-based approach is conducted. Furthermore, the robustness and flexibility in handling variable component sizes is presented. Finalized is the paper with a conclusion on the results and an outlook is given on further development of the proposed algorithm.
