Modelica-Based Simulation Of Electromagnetic Transients Using Dyna Omega O: Current Status And Perspectives

This paper presents the current status, the open challenges, and perspectives for Modelica-based simulation of Electromagnetic Transient (EMT) using Dynamo environment. The simulation efficiency in native Modelica environments requires improvements for larger-scale systems, as they have been primarily developed and used for complex but small problems. This paper investigates the use of Dynamo, an open-source hybrid C++/Modelica tool originally developed for large-scale electromechanical transient studies, for electromagnetic transient simulations. It demonstrates that its approach manages to bring improvements in terms of performances while keeping the flexibility, accuracy, and robustness of full Modelica tools, but that there is still room for further improvements.
