Worked on the oemof-solph repository to improve the accuracy of district heating simulations by addressing a bug in gas boiler efficiency calculations within the project’s tutorials. Focused on backend development and data analysis using Python, the work involved correcting conversion factors to ensure that gas boiler efficiency was represented accurately in district heating supply scenarios. This fix enhanced the reliability of tutorial outputs, which are used by end users for decision-making in energy modeling and optimization. No new features were introduced during this period, with efforts concentrated on refining existing simulation logic to deliver more dependable results for stakeholders.
