Tobias Kluetz enhanced the FINE framework’s documentation in the FZJ-IEK3-VSA/FINE repository, focusing on improving onboarding and technical clarity for users. He integrated detailed mathematical descriptions and expanded information across components such as DC power flow, conversion, storage, and transmission. Using RST and technical writing skills, Tobias introduced new documentation files, restructured existing sections, and updated the main index and further reading areas to reflect the expanded content. His work provided deeper technical context and clearer guidance for users, addressing the need for comprehensive documentation and supporting more effective use of the framework’s diverse modeling capabilities.
