#123: fixing the rectangular formulation

Open hhijazi opened this issue 7 months ago • 0 comments

Description

This PR fixes #123 and corrects the rectangular ACOPF formulation as follows:

  • Formulate the problem without auxiliary variables to avoid feasibility violations.
  • Make sure to add voltage magnitude and phase angle bound constraints in the original space (e,f).
  • Make sure to remove buses that are disconnected (status==4).
  • Make sure to use the correct initial point (setting evar to 1).
  • Compute the voltage angles and magnitudes correctly when using the rectangular formulation.

Warning

The pstart initialization does not work with Gurobi 11, only with Gurobi 12. Therefore the performance on ACOPF will be bad until Gurobi 12. For instance, Gurobi 11.0.2 cannot find a feasible solution on network IEEE69.mat (from #123) after 600 seconds.
