A repository of diverse electric grid test cases, varying in size and characteristics, has been developed for application in power system studies. The purpose of this repository is to provide public access to realistic electric grid models of varying sizes to help facilitate research and education. This repository is regularly updated with new test cases or modifications of existing ones as a result of continuing research. This paper outlines the necessity for this repository, details the electric grids it contains, and provides explanations for the types of cases, highlighting their relevance to different applications.

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. However, the difficulty of obtaining and sharing sensitive transmission grid data has historically presented a challenge for innovation.

To overcome this challenge, PERFORM also funded leading power systems modelling groups at Lawrence Livermore National Laboratory, National Renewable Energy Laboratory, Princeton University, Texas A&M University, and the University of Wisconsin to generate realistic synthetic datasets for the power grid. These datasets served as a basis for the twelve optimization teams to develop their platforms.

The dataset teams have now come together to make their data publicly available via the links below. Each unique dataset can be used for a variety of applications specified by each respective team. ARPA-E hopes that making this data widely accessible will spur additional innovation in grid management beyond the PERFORM program.

Effectively communicating the behavior of an electric grid is an important pursuit in education, research, and industrial applications. Texas A&M University researchers present considerations for visual storytelling as a means for interpreting and communicating the behavior of the grid for simulations ranging in duration from seconds to days. By framing the issue of communicating the vast amounts of data associated with wide-area transmission grid operation as a story to tell, those tasked with presenting this data are encouraged to consider what makes an effective story and, in turn, create compelling and understandable stand-alone narratives. Demonstrations are presented for cases of various scales including a 37-bus case, a 2000-bus case, and a 24,000- bus case.

To encourage and support innovation, synthetic electric grids are fictional, designed systems that mimic the complexity of actual electric grids but contain no confidential information. In order to scale these systems to ten thousand buses or more, robust reactive power planning is needed, accounting for power flow convergence issues. [9] addresses reactive power planning and power flow convergence in the context of large synthetic power grids. Additional complexities can be added into synthetic models to widen their applications. Thus, [10] aims to extend synthetic network base cases for transient stability studies. An automated algorithm is proposed to assign appropriate models and parameters to each synthetic generator. A two-stage model tuning procedure is also proposed to improve synthetic dynamic models and several transient stability metrics are developed to validate the created dynamic cases. A complete list of publications is available here.
