Abstract
This article presents a combined simulation and optimisation technique to
optimise the energy consumption of a single manual-driving train service with
inter-stations along a High Speed Line. For this purpose, the best energy efficient
driving strategies along every stretch between two stations will be simulated with
an accurate and detailed train simulator to obtain the run time and energy
consumption Pareto curves of each stretch. Afterwards, an optimisation tool will
distribute the available slack time for the service among the stretches, which will
minimise the overall energy consumption of the service. The potential of the
method will be shown with a case study at the end of the article.
Keywords: manual energy efficient driving, ecodriving, coasting, timetable,
Pareto curves, slack time.
1 Notation and terminology
Flat-out time: minimum run time that a train can achieve satisfying all the
constraints of a service
Slack time: Time that added to the flat-out time constitutes the commercial run
time of a stretch, and whose aim is to ensure punctuality in case of delays
Grade: Longitudinal track inclination, positive uphills, negative downhills, [‰]
HSL: High Speed Line
Keywords
manual energy efficient driving, ecodriving, coasting, timetable,
Pareto curves, slack time
