Supervisor: Pruckner, M. (2022). Modeling and simulation of sustainable local energy systems (1–) [Master thesis]. University of Würzburg.
- [ Abstract ]
Due to the raising costs for energy and CO2-emission, more and more small companies are interested in new decentralized technologies for CO2-neutral local energy production and storage. For instance, companies with high electricity and/or process-heat demand are interested in photovoltaic and/or solar thermal systems as well as combined heat and power systems (e.g., heat pump - KWK). We want to go one step further: We want to design a new type of system, that will harvest the power of the sun (photovoltaic and/or solar thermal) and provide electricity, warmth and cold (combined heat, power and cooling - KWKK) to use in manufacturing processes. The supply of the energy forms shall be local for self-sufficiency as well as CO2-neutral. The system should be flexible, so that the user can determine which of the three energy forms he/she needs most. Storing electricity will be realized in accumulators while cold and warmth will be stored in insulated water tanks. In this bachelor thesis, a data-driven simulation model should be developed, based on a use case. Based on real and open data different energy system components should be implemented. The model should be used to evaluate different scenarios for sustainable energy supply by varying different parameters such as the size of the photovoltaic system or the capacity of the battery energy storage. Finally, an evaluation of cost savings and CO2 reduction potentials should be revealed.

Supervisor: Pruckner, M. (2023). Passenger transport with minibuses (1–) [Master thesis]. University of Würzburg.
- [ Abstract ]
- [ Download ]
Minibuses are already being used to transport passengers on public transport lines with low demand. Minibus lines are often operated like normal bus lines (based on schedules) or like shared cabs (transport requests must be announced in advance). The question arises whether (and under which conditions) there are better and more efficient strategies for operating a minibus line. In this context, there are various questions that can be addressed in the context of a final thesis. An interesting task would be the creation of a concrete test instance based on already operating or planned minibus lines, the development of a simulation that allows to test and compare different strategies, and the development and (experimental and/or theoretical) analysis of strategies.
Supervisor: Pruckner, M. (2023). Charging planning for electric buses (1–) [Master thesis]. University of Würzburg.
- [ Abstract ]
- [ Download ]
If a transit agency replaces part of its conventional bus fleet with electric buses, the allocation of buses to trips must be rethought to allow for sufficient charging time between trips for the electric buses. Factors such as fluctuating electricity prices, temperature-dependent energy consumption should also be considered. In preliminary work, this optimization problem was modeled as a mixed-integer linear program, which in principle can be used for potential studies ('How much energy could have been maximally saved for a specific time period by using electric buses?'), but in its current form can only be used for very short time periods due to its long runtime. The task of this thesis is to find an approach, based on the present model, to solve the problem for longer time periods (such as one year). For this, different (exact or heuristic) approaches are possible, for example a (partial) re-formulation of the model or a 'rolling horizon' approach (where the model is solved step by step for shorter, overlapping time periods. It would further be interesting to adapt the model for use in operational planning, where future energy prices and temperature conditions are subject to uncertainty.
Supervisor: Strobel, L. (2022). Electrification of public transport in European towns - A case study of Bayreuth (1–) [Master thesis]. University of Würzburg.
- [ Abstract ]
The electrification of public transport is a major milestone towards carbon neutrality. This process is well on its way in large urban centers, but in smaller towns, the vehicle inventory still primarily consists of fossil-fuel-powered buses. Significant uncertainty about the economic and practical feasibility of full-electric fleets is prevalent among stakeholders. At the same time, public transport is uniquely qualified for smart-charging use cases due to the centralized control of the transport authority and the highly predictable nature of driving patterns. This thesis aims to evaluate the feasibility of switching to an all-electric bus fleet in Bayreuth and the resulting smart-charging revenue potential. This work is part of ESM-Regio, a project in partnership with Stadtwerke Bayreuth, and real-world data is available. The thesis includes: - Literature research - Analysis of the available data - Development of electric bus model - Development of a charging optimization model - Scenario analysis Requirements: - Knowledge of any programming language Helpful: - Experience with data analysis - Experience with mathematical optimization (We can do a crash course)

- [ Abstract ]
Goal of this work is the design and implementation of a web-based application that allows the graphical configuration of service function chains (SFC). An underlying backend (written in R) should then perform detailed performance evaluation (discrete-time modeling, simulation) of the designed SFC and generate several key performance indicators of the system.
