Worked on the pandapower repository to enhance the CIM2pp data conversion process by introducing the EquipmentContainer_id field to the line mapping, thereby improving data fidelity for AC line segments. This targeted update focused on refining the mapping logic without altering core functionality, ensuring that the data structure better supports traceability and quality objectives. The implementation was carried out using Python and leveraged expertise in CIM Model and data conversion techniques. Documentation was updated in reStructuredText (rst) format to clearly record the change, maintaining transparency and supporting future maintainability. No bug fixes were addressed during this period, focusing solely on feature delivery.
