How do you define the parameters like X source , Subtransient,Transient,Synchronius, Zero and Negative impedance while modeling ? What values to be considered ?

This question was brought out because a certain utility requires that during fault, the solution must still converge. I am working on disturbance simulation for simple system with Solar PV Plant under study.
Would appreciate to know if there's such statement from the manuals or any valid reference.fflThu, 14 Mar 2019 21:32:47 -0500http://psspy.org/psse-help-forum/question/5711/If Solar Generation increases in a power system, what is the expected effect on Rate of Change of Frequency (RoCoF)?http://psspy.org/psse-help-forum/question/5147/if-solar-generation-increases-in-a-power-system-what-is-the-expected-effect-on-rate-of-change-of-frequency-rocof/ Hi,
I am getting decreased RoCoF for increasing solar generation in my simulation result.
I have doubt how valid this effect is? I used a simple formula to calculate this:
RoCoF= (Change in Frequency from Nominal Value till Frequency Nadir)/ (Time Required for this change)
For example: if the system frequency is 50 Hz and the frequency Nadir is 49.5 Hz and it took 0.5 Sec to go from 50 to 49.5 Hz, then according to the above mentioned formula,
RoCoF = ((50-49.5)/0.5) (Hz/Sec)
Can anybody please guide me about this basic queries?

Can we use any control mechanism for stabilizing Solar PV generator after a fault occurance?
The way we use PSS for Synchronous generator power output stability.
