Electric Power Library

The Modelica Electric Power Library is ideal for efficient modeling, simulation and analysis of electric power systems, including AC three-phase (abc, dq0, dq) and one-phase AC and DC systems. The models can be used in both steady-state and transient mode for simulation and initialization.

The library’s components provide standardized interfaces to thermal and mechanical domains, and are easy to combine with other libraries to represent electric power and actuation. Application domains include power stations and rail vehicles.


  • Provides multi-domain capabilities — power electronics, mechanics and thermal dynamics can be captured in the same tool, saving time and simplifying modeling
  • Transient and steady-state (electrical part only) simulations reflect real-world scenarios
  • Easily integrated into any application domain
  • Well-suited for control design applications where it is valuable to simulate behavior early in the design process.
