Use Digsilent to get Voltage Sensitivities

[PalaUth]

Hello,

I am working on a project using Digsilent Power Factory Workstaion. I have a problem in calculating voltage sensitivities using the buil-in function. I have used the unbalanced load flow and it is giving me all sensitivities zero. I cannot understand where I am going wrong. Appreciated if I could get an advice and a reference to look at. The manual doesn't provide any guidance for unbalanced condition.

Thank you

Do you have any single phase loads or unbalanced three phase loads?
