powerio-prob

A problem instance is the complete numerical input for one problem family. It contains indexed coefficients, bounds, mappings, units, and conventions. It is separate from the source network, matrix projections, solver formulations, and solutions.

powerio-prob, short for problem instance builders, assembles these instances from PowerIO models.

The default build has no sparse matrix dependency. It provides index based DcOpfInstance and AcOpfInstance data whose bus, generator, and branch arrays can be consumed directly by an operations research model, and a matrix free ScopfInstance for GOC3 data. Relaxations of AC OPF, the SOC forms included, consume the same AcOpfInstance. Enable the matrix feature to derive sparse DC OPF operators from a DcOpfInstance.
