Hi Dr. Zimmerman, I encountered a problem while using matpower. DCOPF cannot converge on one case, **even after setting branch capacities to be all 0 (infinite)**. **Then I used toggle_softlims...

how to identify relaxed constraints?

Hi Dr. Zimmerman, I encountered a power flow case that could not be converged using DCOPF. However, after using toggle_softlims to relax some constraints, the DCOPF problem was able to...
