When you start doing research on power systems, you often spend a lot of time on searching power system models to test your developed theories and methods. In the following, I am listing a number of power system test archives, where you can find static and dynamic power system models.
If you are aware of other power system model archives/repositories, which are missing in the list, or if one of the links is not working, please leave a comment at the end of this page.

University of Liège – Voltage Stability Test System
At the University of Liège a test system called Nordic System was developed, which is specifically intended for the study of voltage stability phenomena.
- Nordic System: Static and dynamic system parameters.
Access to the system model can be granted by Prof. Van Cutsem. The power system model is documented in a report, which will be provided together with the system model.
The IEEE PES Task Force on Test Systems for Voltage Stability Analysis and Security Assessment published on August 25, 2015 their report on “Test Systems for Voltage Stability Analysis and Security Assessment” (Technical Report PES-TR19) [3]. The report gives detailed information about two test systems, one of them being the Nordic System. The report contains network data and dynamic model data for e.g. synchronous machines and their controls. Moreover, the report provides data for two operating points (a stable and an unstable operating point). Lastly, the report discusses the issues of determining secure operation limits, power margins and corrective post-disturbance controls with respect to long-term voltage stability. For members of IEEE PES the report is free of charge available on the website of IEEE PES in the Technical Reports section.
University of Cyprus – Dynamic IEEE Test Systems
A group of researchers at the Center for Intelligent Systems & Networks (KIOS) has extended a number of the IEEE Test Systems with dynamic model data appropriate for carrying out time-domain simulation. The researchers derived the model parameters based on typical model data described in [4]. The dynamic model data are freely available on their website and are provided in different formats:
- Plain text (*.pdf)
- PowerWorld (*.pwd/pwb)
- DIgSILENT PowerFactory (*.pfd)
Moreover, the test system data are documented in [5].

- IEEE 14 Bus Test Case: Plain text, PowerWorld and DIgSILENT PowerFactory.
- IEEE 30 Bus Test Case: Plain text and PowerWorld.

ALSETLab – Nordic 44
The research group of the ALSETLab has developed and uploaded Python resources to fetch and process the Nordpool market data to prepare case files in Modellica, COM 14 and PSS/E. The python scripts with some documentation can be found here on GitHub.
The available model is the Nordic 44, which was developed as an equivalent Nordic grid model.
Energinet: Danish static power system model
On Friday January 22nd 2016, the Danish transmission system operator Energinet announced on LinkedIn that they published a first edition of a static power system model of the Danish transmission grid.
The provided data are sufficient to calculate an AC power flow and represent the 2020 Danish transmission system until the country’s borders. Currently, the model data are available in a simple spread sheet format. However, Energient is planning to publish the model in the CGMES-format at a later time.
The power flow data can be downloaded here.
ENTSO-E: Power system model of continental Europe
The European network of transmission system operators for electricity (ENTSO-E) published at this year PowerTech in Eindhoven, Netherlands, a dynamic study model of the entire continental Europe power system. The model is documented in a paper [6], which was published as part of the proceedings and can be dowloaded from the website from ENTSO-E. According to the website from ENTSO-E the data (load flow and dynamic data) are available in three different formats: PowerFactory, Netomac and PSS/E. However, the access to the data is restricted and more information can be found on the website.
