Dynaωo: A Hybrid C++/Modelica Open-Source Suite of Simulation Tools for Power System
summary
Dynaωo is a Hybrid C++/Modelica open‑source simulation suite that separates equation‑based models from solvers, uses Modelica for component behavior and C++ for core and solver interfacing, and already exposes 150 public models. It runs daily operational workflows (dynavals used in operation since 2022), handles mixed continuous/discrete controls (HVDC with 50 s filter, PST step times ~2–5 s) and reports less conservative transfer limits than static power flow on tested French–Spanish cases.
