3 Commits • 2 Features

Mar 1, 2025

March 2025 monthly summary for e2nIEE/pandapower: Delivered key UCTE workflow enhancements and a critical robustness fix. Key features: 1) UCTE to pandapower conversion now includes ucte_country on bus objects, providing geographical context for grid studies; 2) Added slack_as_gen parameter to from_ucte and from_ucte_dict to optionally convert slack elements as generator elements. Major bug fix: robust handling of None values in the tap dependency table by interpreting None alongside NaN as False, improving tap calculation reliability with incomplete data. Overall impact: improved data fidelity, geolocated bus attributes, and flexible slack conversion, reducing manual data curation and enabling more accurate power system modeling. Technologies/skills demonstrated: Python-based ETL, UCTE parsing, robust handling of NaN/None, version control and maintainability.

October 2024: Documentation updates for API Geography Data Access in pandapower (e2nIEE/pandapower). Updated docstrings to reflect API changes in geographic data access: net.line_geodata -> net.line.geo and net.bus_geodata -> net.bus.geo, and fixed a minor typo in the data modification toolbox logging. These changes align the docs with the latest API and improve developer experience, reducing onboarding time and support overhead. The work enhances maintainability and transparency for users relying on geographic data access.
