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.
Manual runs of PSSe use an AC load flow solution method, taking into account the reactive power effect on the MVA flow reported, while activity ACCC uses linear factors (like PTDF or OTDF) calculated by activity DFAX, to evaluate the effect of a contingency on the MVA flow monitored (kind of DC load flow). Both values will differ the most when the contingency creates large delta in P & Q flows.
Thanks for the explanation
