Texas2k Series24 Cases with Improved Dynamics
This dataset download includes six Series24 dynamics cases for the Texas2k system, a synthetic Texas case with scenarios varying in loading levels, renewable penetration, inertia, and inverter controls.
Hawaii Synthetic Grid — 37 Buses
This is a smaller, geographically-embedded, self-contained island test case, which contains a synthetic 138/69 kV transmission network on the geographic footprint of the Hawaiian island of Oahu.
Texas Synthetic Grid — 6717 Buses
This test case covers the geographic footprint of the ERCOT portion of the US state of Texas with a 6717-bus transmission network at the 345/138/69 kV levels. (Also available with distribution and with natural gas pipelines.)
Combined East-West US Grid – 80,000 Buses
This very large synthetic case models the footprints of the US portion of the eastern and western interconnects, as if they were synchronously inter-tied to form one combined grid.
Datasets for ARPA-E PERFORM Program
ARPA-E’s Performance-based Energy Resource Feedback, Optimization, and Risk Management (PERFORM) program seeks to develop new grid management systems that represent the relative delivery risk of individual electricity generation resources and balance the collective risk of all assets across the grid. The program has funded twelve project teams across the country to build software platforms that optimize grid management as the penetration of variable renewable resources continues to increase.

Synthetic Cases from ARPA-E GridData Program
Synthetic electric grid models are fictitious representations that are designed to be statistically and functionally similar to actual electric grids while containing no confidential critical energy infrastructure information (CEII). Some of these cases were developed with the support of the U.S. DOE ARPA-E Grid Data program; their support is gratefully acknowledged. Specific references for the creation and validation of these cases here.

About
All cases displayed above include a feasible AC power flow solution. Icons next to each case indicate whether additional parameters/models are included: TS for transient stability, GMD for geomagnetic disturbance analysis, OPF for energy economic study, PWDS for PowerWorld Dynamic Studio scenarios, MOV if case movies are available and PMU if synthetic PMU data is available.
Here are some introductory videos showing how these interactive power system simulation cases improve the situational awareness of current system operating conditions.
