Focus Topic
An hybrid C++/Modelica open source suite of simulation tools for power systems
Primary Purpose
Dynaωo is an hybrid C++/Modelica open source suite of simulation tools for power systems. It aims at providing power system stakeholders with a transparent, flexible, interoperable and robust suite of simulation tools that could ease collaboration and cooperation in the power system community.
Description
Dynaωo is an hybrid C++/Modelica open source suite of simulation tools for power systems. It aims at providing power system stakeholders with a transparent, flexible, interoperable and robust suite of simulation tools that could ease collaboration and cooperation in the power system community.
To achieve this goal, Dynaωo is based on two mains principles: the use of a high-level modelling language Modelica and a strict separation between the modelling and the solving parts.
Dynaωo ‘s primary focus has been on long-term and short-term stability studies but the very encouraging results obtained and the flexibility of the approach led to an extension of the initiative. Dynaωo is now evolving towards a complete and coherent suite of simulation tools, sharing the same philosophy:
More information is available on the project website.
Mathematical Description
Dynaωo represents the power system behavior by a set of differential-algebraic equations (DAE). It comprises a large number of stiff, non-linear, sparse,differential and algebraic equations, augmented by discrete-time equations to define the evolution of the discrete variables

Use Cases
Dynaωo can be used for any stability study on regional to continental systems. It allows to do steady-state calculations as well as time-domain simulations, from long-term stability to EMT simulations. It is notably used in French control centers for voltage stability assessment and for some calculations on the borders.

Interface, Integration, and Linkage
Dynaωo is interfaced with the PowSyBl project, both for steady-state calculations and long-term stability calculations. The other domains will be interfaced in the next few months (https://github.com/powsybl/powsybl-dynawo).
Dynaωo also proposes a certain number of advanced algorithms such as contingency analysis, voltage margin calculations or critical clearing time: there are available in a dedicated repository - https://github.com/dynawo/dynawo-algorithms.
