Energy Scheduling Optimisation at SBB

The supply of electricity is essential to SBB. While most of it is produced and used by SBB itself, current is also converted to and from the household power grid. These operations shall be conducted cost-efficiently and require sound planning assisted by the software described in this project.

Energy production and procurement is carefully planned by SBB Energy employees on various time horizons. Since 2015, they have been supported by the optimisation software “OptRe”. The tool is mainly used to generate possible energy schedules for defined periods based on forecast data. Since its introduction, OptRe has been continuously developed further. As the contract with the current supplier will run out in the next years, a new public tender will be required. The current and future optimisation-related architecture, as well as a set of requirements, is to be developed by the student.
A literature review was conducted to gain the necessary familiarity with the topic. The enterprise architecture related to energy trading and optimisation was then developed, and the requirements for the successor software were systematically collected and filed. A target architectural model was created, which depicts the changes brought by projects currently underway. The documentation work was performed mostly based on pre-existing materials. All models have been verified during the project, and the validation of the requirement set is planned to be carried out after the student project.
The architecture work was carried out using the architecture framework TOGAF and the associated modelling language ArchiMate for the first time in the context of SBB Energy. Therefore, the procedure and results were documented and evaluated in detail. Advantages and disadvantages of using TOGAF and ArchiMate during requirements elicitation are presented, and general recommendations on the use of these methods are given. The set of methods is considered to be very helpful, as the frameworks complement each other perfectly. Many isolated artefacts from TOGAF become obsolete thanks to ArchiMate. With the set of methods, complex facts and interrelationships can be modelled with little effort. The first experience shows that the models are rapidly understood by stakeholders. They can, therefore, be used as a valuable basis for discussion in project work. The further use of these frameworks is hence strongly recommended. The information documented has the positive side effect that it serves as a valuable source of knowledge for other project teams. It may allow them to familiarise themselves with the structure of the optimisation solution, how it works, and with the changes to come.
