M. Sc. Marius Kühne and M. Eng. Albert Nebe from the Faculty of Engineering receive prize for their Master's theses on optimised energy management with the integration of photovoltaic power generation
Every year, the Leipzig Energy and Environment Foundation awards a prize of 1,000 euros per category for outstanding theses and dissertations as well as innovative scientific project work in order to promote young talent and intensify cooperation with scientific training and research institutions in the city and region of Leipzig.
Master's student Marius Kühne, a graduate in electrical engineering and information technology, and Master's student M. Eng. Albert Nebe, graduate of Energy, Building and Environmental Engineering from the Faculty of Engineering Sciences (ING) at HTWK Leipzig, impressed the foundation's jury with their theses and were presented with the sponsorship awards at a ceremony on 8 February 2024.
Energy and environment
M. Eng. Albert Nebe received the sponsorship award in the "Energy and Environment" category for his thesis "Minimising electricity generation costs at the Cröbern central landfill site through optimised dimensioning of power plant and storage units". M. Sc. Seyfarth from Westsächsische Entsorgungs- und Verwertungsgesellschaft mbH supervised the work on the entrepreneurial side. Prof Winfried Hähle, Professor of Electrical Engineering in Mechanical Engineering at the ING Faculty of HTWK Leipzig, supervised the award-winning master's thesis.
In his master's thesis, M. Eng. Albert Nebe analysed the extent to which the electricity generation costs of the Cröbern central landfill site could be reduced by installing an additional photovoltaic system, a combined heat and power plant and a gas and battery storage system. The aim was to optimise the dimensions of the planned new systems for power generation and storage for interaction in the local medium-voltage grid of WEV mbH. There was an optimisation problem with five variables and the target value, electricity production costs of the location. The optimisation problem could be solved for different scenarios of future market prices by means of the structured and successive development of a holistic Excel model, which includes all parameters and variables.
Implementing the optimised energy concept would double the site's degree of self-sufficiency on average over the twelve-year period from 2024 to 2035, which would significantly improve the company's carbon footprint.
Since successfully completing his studies, Albert Nebe has been able to contribute to the implementation of this energy concept as part of WEV and at the same time be the contact person for new optimisation issues.
Energy networks and data networks
M. Sc. Marius Kühne received the sponsorship award in the "Energy Networks and Data Networks" category for his master's thesis entitled "Optimising self-consumption in residential energy management using machine learning methods against the backdrop of the smart grid". The thesis was supervised by Dr Thomas Stöter from TQSystems GmbH and Prof Andreas Pretschner, Professor of Process Informatics in the ING Faculty at HTWK Leipzig.
Kühne's master's thesis is dedicated to the development of a learning system for optimising the self-consumption share of private households with photovoltaic systems using generation forecasts. With the help of neural networks, he creates a forecast that is fed by solar radiation data, a clear-sky model and weather data. Based on the information obtained, Kühne has created an energy schedule by comparing it with consumption data. The aim of self-consumption optimisation is to use anticipated surpluses intelligently for the company's own requirements. To this end, Kühne developed an application in the supervising company that can determine optimised parameters for the hybrid charging of an electric car depending on PV surplus forecasts.
The Faculty of Engineering congratulates its award-winning Master's students and wishes them every success in their future projects and endeavours.
Background: Award of the Energy and Environment Foundation Leipzig
The foundation has set itself the goal of promoting Leipzig-Halle as a centre of excellence for promising and environmentally friendly energy technologies and thus strengthening the economy of the Central German region, which is to be achieved by awarding sponsorship prizes, among other things.
Every year, graduates and young scientists from universities and research institutions in the city of Leipzig and the Leipzig region have the opportunity to apply for one of the foundation's two sponsorship awards with their final thesis or project work.
The "Energy and Environment" prize is awarded for the best research and development work that deals with environmentally friendly technologies for the generation and utilisation of energy resources or processes and methods for the rational use of energy and energy saving, as well as the MSR technology required for this.
The "Energy Networks and Data Networks" prize is awarded to the best research and development work that deals with the topics of decentralised energy supply systems, SMART GRIDs, communication technology in energy generation systems, simulation of interconnected electrical networks, regulation and control of complex energy supply systems or monitoring and diagnosis in energy supply systems.
