eGo^n

After graduating from high school in Braunschweig in 2006 and spending a voluntary social year in Panamá, Ulf Philipp studied energy and environmental management (industrial engineering) at Flensburg University of Applied Sciences. The Bachelor in Flensburg was enriched by a semester abroad in Granada, Spain in the field of economics and intercultural skills. In the subsequent practical semester, he was able to gain intensive experience in project planning for large PV parks in the International System Design department at Juwi Solar GmbH. He wrote his bachelor's thesis on "Temperature-dependent voltage extremes in photovoltaic systems" on behalf of Juwi.

Parallel to his master's degree, he was able to develop a business plan for the economic project planning of small wind turbines and the development of decentralized smart grids as part of a start-up grant from the Schleswig-Holstein Innovation Foundation together with two fellow students. In his master's thesis, he evaluated the extent to which systematic voltage conversions in the medium-voltage grid of Schleswig-Holstein Netz AG make technical and economic sense for E.ON Hanse AG.

Since May 2013 he has been working at Flensburg University of Applied Sciences as a research assistant in the field of energy and environmental management in the energy and biotechnology department. His focus is in the context of a sustainable and continued reliable power supply. He is therefore particularly concerned with a needs-based system integration of renewable energies.

From 2015 to 2018 he worked in the research project open_eGo [26905], which he initiated, coordinated and significantly designed. Since 2019 he has been working in the follow-up research project eGo^n on the integration of sector coupling effects into the existing power grid planning tools.

At the beginning of 2021 he submitted his doctoral thesis "Combined optimization of grid and storage expansion in the German electricity system", which he successfully defended in April 2022 and is about to be published.
