Thanks for the explanation

Hi, I have had this problem on two projects now. When getting line flows using result = pssarrays.accc_solution() and then result.mvaflows This gives a different value then if I go into psse and manually turn a line off then check the line flows.

Thanks for the comment, I thought this might have been the case so I tried using psspy.non_trans_percent_units(0) to change what the branch was calculated with and I still have the same issue.

2023-12-20 17:09:53 -0500 asked a question ACCC overload report issue

Hi,

I'm currently looking at doing some ACCC. I have a loop that uses,

pssarrays.accc_summary

and,

pssarrays.accc_solution

to loop through each contingency and check if the MVA flow is greater then the rating of the line. In my code this shows a line overloaded. But when I use,

psspy.accc_single_run_report_5

showing the overload report it says there are no overloads. Any ideas why? Or which method is actually correct?

Cheers
