Hello,

I am using the following skip block structure in a .con file to skip the branch from Bus 100 to Bus 200. Bus 100 is in Subsystem 'ABC'

SINGLE TIE FROM SUBSYSTEM 'ABC'

SKIP LINE FROM BUS 100 TO BUS 200 CKT 1 FROM BUS 200 TO BUS 100 CKT 1 END

But I still see the Contingency "SINGLE OPN TIE 65 100-200(1)" in the list of events. Can someone help me with skipping the branch in automatic contingency specification in PSS/E 35?

Hello,

Is it possible to perform sensitivity analysis for a set of contingencies?

I am using 'psspy.sensitivityflow' or 'pssarrays.sensitivityflowtomw' and giving the con file in Dfax preparation.

But I see that sensitivity factors are calculated for only the base case. However, I need the sensitivity factors to be calculated under all the contingency events. Will that be possible with this command?

Thanks for any help.

Hi,

I am trying to extract the results of acc files using pssarrays.acccsummary and pssarrays.acccsolution. I have more than 80,000 contingencies. When I try to read the result of each contingency using for loop in python, I get MemoryError after reading 8,000 contingencies. The size of my .acc file is 2GB

Since I am working with large datasets, will Dask be helpful for this issue? Did anyone face a similar issue?

Any suggestion is greatly appreciated. Thanks in advance
