PROFILE
Landry Huet
Over three months, contributed to the powsybl-core repository by delivering four features focused on HVDC and DC network modeling. Developed Java-based import functionality for MTDC subnetworks and DC switches from DGS files, enhancing data structures for deterministic traversal and efficient lookups. Introduced topology-aware resistance attributes for DC switches and active power limits for AC/DC converters, aligning with IIDM 1.17 standards. Emphasized robust backend development through expanded unit testing, improved serialization, and comprehensive documentation updates. The work demonstrated depth in API design, network modeling, and full stack development, addressing real-world requirements while maintaining code quality and backward compatibility.

May 1, 2026May 2026: Delivered DC Switch Resistance attribute with topology-aware computation in powsybl-core, aligning with IIDM 1.17 and enabling topology changes when resistance is non-zero. Enhanced topology computation and adjacency logic to account for the new resistance feature, with thorough tests and documentation updates. Prepared groundwork for PyPowSyBl integration, including serialization behavior adjustments and IIDM version compatibility, while maintaining backward compatibility.
