PROFILE
Chiaramello Marco
Over six months, contributed to the dynawo/dynawo repository by developing and refining power systems simulation features using C++, Modelica, and Python. Delivered enhancements such as a discrete secondary voltage control model and saturation-limited integrators to improve voltage and reactive power regulation stability. Implemented HDF5-based curve export for scalable data management and addressed edge-case transformer impedance bugs to ensure simulation reliability. Integrated new models with CMake, maintained repository hygiene, and provided comprehensive unit and regression tests. The work emphasized robust control systems, embedded systems, and data visualization, supporting accurate analytics and reliable automation for power systems planning and operational studies.

Apr 1, 2026April 2026: Delivered a focused bug fix in transformer impedance handling for dynawo/dynawo to prevent division-by-zero when both resistance and reactance are zero. The fix defaults reactance to 0.01 in such edge cases, mirroring existing line impedance behavior, and includes regression/unit tests to ensure ongoing stability. This change enhances the reliability of transformer models in grid studies and prevents erroneous results during edge-case scenarios. The work is delivered with a minimal surface area, backed by a targeted test suite and a single commit.
