Control of Energy Storage Device for Rail Vehicles

- Abstract
- This master thesis has been done in Berlin at Daimler Chrysler. It is concerned with technological research and development for electrical engine. This thesis treats to evaluate what margins can be achieved by using energy storage system on rail vehicle.
Energy storage devices, like accumulator, flywheels or capacitors are currently under consideration by the rail vehicle industry. The expected benefit introducing storage systems is not only reduced energy consumption but also advantages concerning reduced line peak loads, network stabilisation, improved driving performance.
These devices are able to store kinetic energy during the brake time and feed it back during acceleration or during max power demand.

Energy storage devices, like accumulator, flywheels or capacitors are currently under consideration by the rail vehicle industry. The expected benefit introducing storage systems is not only reduced energy consumption but also advantages concerning reduced line peak loads, network stabilisation, improved driving performance.
These devices are able to store kinetic energy during the brake time and feed it back during acceleration or during max power demand.
The work is divided into two steps:
- A simulation model of the vehicle’s drive and energy storage system has to be set up using ”Matlab”. Multi-objective optimisation has to be applied using, e.g., non-linear programming or evolutionary strategies. The results, at this stage, are optimised cycles for the storage operation depending on given sets of track profiles and driving cycles. These results are not necessarily already under control laws. The problem of reduced run-time information is also not considered at this stage.
- During the second step, the results of step one must lead to a control law for the energy storage device that is suitable for run-time implementation and that is able to deal with the mentioned reduced information. General control design principles should be derived. It should be evaluated, what margins can be achieved compared with those of step one. Simple control laws should be specified for following next controller implementation.
The proposal of the research work is to determine a control law that permits to utilise in optimal way the energy storage device in such way to centre the prefixed objective, like reduced energy consumption, advantages concerning reduced line peak loads, network stabilisation, improved driving performance. All this without knowing in advances the characteristic of the route, the brake and acceleration moment. The control law must be set up in Real-time context. (Less)
