But he problem can be solved with Active set option correctly, by using the same stating point. Thanks

It may in fact not be a problem with either, but rather that the problem you specified is infeasible. But, as I said, I have no way of knowing. -- Ray ZimmermanSenior Research AssociateB30 Warren Hall, Cornell University, Ithaca, NY 14853phone: (607) 255-9645 On Feb 10, 2014, at 8:44 AM, amel zerigui <[email protected]> wrote:Hi, I changed the equality constraints of matpower by adding new constraints, in same way I changed also the Jacobian matrix, and when I checked the computed first derivative, I found this result: Nonlinear equality constraint derivatives: Maximum relative discrepancy between derivatives = 4.44985e-009 This mean the modification is correct, then I estimated the hessian by using BFGS but the optimal point found is: No feasible solution found. I would like to know if the problem is Matlab problem or Matpower. Thanks for help.
