Test Systems for Voltage Stability Analysis and Security Assessment (PSDP Committee)
IEEE Product posted 25 August 2015. Report is available free to PES members.

This report documents the work of the IEEE PES Task Force on Test Systems for Voltage Stability Analysis
and Security Assessment. The report starts with a short introduction about the motivation and the scope of
the work. Next, the models of respectively the Nordic and the RVS test systems are presented in detail, together
with a sample of long-term dynamic simulations of their responses to large disturbances. Appendices
are devoted to complementary analyses and simulation results obtained with other time-domain simulation

The system data and a sample of representative outputs will be available on a Web site maintained by
the Dynamic Security Assessment Working Group of the Power System Dynamic Performance Committee
(please refer to for more information).

Benchmarking and Validation for Cascading Failure Analysis Tools (IEEE Working Group on Understanding, Prediction, Mitigation and Restoration of Cascading Failures ) This test case is under development.  To participate, contact these persons:

The IEEE-PES-PSACE-Intelligent System Subcommittee (ISS) Working Group on Intelligent Data Mining and Analysis has some some data sets for case studies published in its WG website.  Each data set can be accessed trough the respective web link.

Non-IEEE Test Cases

Through the ARPA-e GRID DATA program, a number of large-scale “realistic but not real” test systems for both transmission and distribution systems have been developed. These and a large number of other test systems are available at the two GRID DATA funded websites:

Power Systems Test Case Archive (hosted by University of Washington)

Matpower link (hosted by PSERC at Cornell.) MATPOWER is a package of MATLAB® M-files for solving power flow and optimal power flow problems. It is intended as a simulation tool for researchers and educators that is easy to use and modify.
