PSSE models require the STATE to be stabilized at initialization (DSTATE=0)

The 4th STATE (=K+3) of the CBEST is the 'Energy Output'.

If the CBEST has an initial output, there will be an Energy change because the CBEST's output is not zero initially. As a result, the STATE is not constant and DSTATE is not zero.

Your error message probably looks like this below

i dstate(i) state(i) model state bus# x-- name --x baskv id

num 0.2000 0.0000 CBEST K+3 busnum busname basekv id

Please refer to the link below https://psspy.org/psse-help-forum/que... Hope this helps you.
