There was a problem hiding this comment.
Looks good to me, and works for HiOp MDS (PBPOLHIOP and PBPOLRAJAHIOP).
There is a bug that prevents testing the Ipopt case (setting isTestOpflowModelPBPOL = true in test_acopf.cpp, line 68), when the inequality constraint Jacobian is not present (case118). That can be fixed in a subsequent PR.

Summary
Line thermal constraints are strictly positive so the lower bound on line constraints in the optimization model should not be set, i.e. it is negative infinity. This fix was made to power balance polar and sparse models but not to mixed dense-sparse (MDS) models. This PR addresses this.
This PR also updates answer keys for the related tests.
