Trams brake electrically and generate energy in the process. If no other vehicle takes it up, it is converted to heat in braking resistors. Storage units along the line can absorb it. Where they should be placed and how large they should be depends on the timetable and the network.
- Setting: research and development at TII Energy GmbH & Co. KG (flywheel storage)
- Tools: Matlab, Simulink, SimPowerSystems, XML
My contribution
- A modular simulation model of the electrical rail network
- Automatic generation of the Simulink model from track and network data in XML
- Energy demand per track section from elevation and curve profiles
- Timetables and load cycles in tabular form, substation locations and the direction of travel on both tracks as inputs
- Adjustable simulation accuracy, automated evaluation of the simulation data
- Optimisation of storage location and size with evolutionary algorithms, coupled to the model via XML
Outcome
- A simulation tool that transfers to other networks, such as AC or DC networks in industrial plants
