 This benchmark library is curated and maintained by the [IEEE PES Task Force on Benchmarks for Validation of Emerging Power System Algorithms](https://power-grid-lib.github.io/) and is designed to evaluate a well established version of the the AC Optimal Power Flow problem.  An introductory video is available [here](https://youtu.be/fC3hzddCJ2c). Specifically, these cases are designed for benchmarking algorithms that solve the following Non-Convex Nonlinear Program,
