Hi, There you go. The results are similar as compared with ‘makePTDFac’ for my test cases (1 slack and rest all PQ buses). Thanks, Sarmad

I’m not sure whether it is correct, but it has some test code as well. If you have the time to check it out, confirm that it works or fix it if necessary, maybe we could include it in MATPOWER.

In MATPOWER, makeJac(‘your case file’) can be used to calculate the Jacobian. Hope this helps.

Is there any way I can achieve the ACPTDF? Kindly assist with possible suggestions to the problem.
