Hi Matpower Community, I was testing the application of reactive capability curve limits. I defined a generator operating region by using the points described in section 6.4.3 in the manual. I first performed the OPF without including the parameters, and then compared it with the results when the PQ curve limitation was included. I was expecting the same results because the operating point is very well within the operating region defined by the limits. But the results were two slightly different operating points. Is this really how Matpower behaves? I am attaching the two case files, in case. Thank you very much!
