ML-OPF-Bench

AC/DC optimal power flow samples, reference solutions, dual labels, and network constraints for the IEEE 30-, 118-, and 300-bus systems.

Code and quick start

Layout

  • ac_dataset/acopf_datasets/: AC loads, solutions, and duals.
  • ac_dataset/acopf_constraints/: AC network parameters and limits.
  • dc_dataset/dcopf_datasets/: DC loads, solutions, and duals.
  • dc_dataset/dcopf_constraints/: DC network parameters, limits, and PTDF matrices.

The 118-bus data include larger-variance and API scenarios. Load the corresponding scenario constraints through the benchmark code.
