Power Grid Lib - Optimal Power Flow

This benchmark library is curated and maintained by the IEEE PES Task Force on Benchmarks for Validation of Emerging Power System Algorithms and is designed to evaluate a well established version of the the AC Optimal Power Flow problem. An introductory video is available here. Specifically, these cases are designed for benchmarking algorithms that solve the following Non-Convex Nonlinear Program,

  The Mathematical Model of the Optimal Power Flow Problem  

A detailed description of this mathematical model is available here. All of the cases files are curated in the Matpower data format. Open-source reference implementations are available in Matpower and PowerModels.jl and baseline results are reported in BASELINE.md.

Problem Variants

These cases may also be useful for benchmarking the following variants of the Optimal Power Flow problem,

  • DC Optimal Power Flow
  • AC Optimal Transmission Switching
  • DC Optimal Transmission Switching

That said, these cases are curated with the AC Optimal Power Flow problem in mind. Application to other domains and problem variants should be done with discretion.

Case File Overview

A forthcoming technical report will detail the sources, motivations, and procedures for curating these case files.

In this repository the network data files are organized into the following three broad groups:

  • /*.m - base case benchmarks as originally specified
  • /api/*.m - heavily loaded test cases (i.e. binding thermal limit constraints)
  • /sad/*.m - small phase angle difference cases (i.e. binding phase angle difference constraints)

Contributions

All case files are provided under a Creative Commons Attribution License, which allows anyone to share or adapt these cases as long as they give appropriate credit to the orginal author, provide a link to the license, and indicate if changes were made.

Community-based recommendations and contributions are welcome and encouraged in all PGLib repositories. Please feel free to submit comments and questions in the issue tracker. Corrections and new network contributions are welcome via pull requests. All data contributions are subject to a quality assurance review by the repository curator(s).

Citation Guidelines
