Optimal Charging Infrastructure for Electrified Public Transport

There is a trend towards electrification of urban public transport systems.

Benefits are e.g. reduced air pollution and noise, increased passenger comfort, cost reductions, and making renewable fuels available for other applications.

Many technical solutions are available, e.g. buses with large batteries that are charged at depots, or buses with smaller batteries that are charged at bus stops or during driving.

The evaluation of which combination of these subsystems that is most cost- and resource efficient is a complex task, that depends on the cost of batteries and charging infrastructure.

Therefore, it is valuable that we in this project develop mathematical models to find optimal solutions in a systematic approach.

To achieve a realistic overall system with high flexibility, we will use timetables and data from an existing bus system, including GPS positions and momentary energy consumption of the buses. Aging and environmental impact of the batteries will also be considered.
