try to adjust the solution settings some time the time step and acceleration factor are not suitable with your .dll try this psspy.dynamicssolutionparam2([200,i,i,i,i,i,i,i],[ 0.2,f, 0.000833, 0.004,f,f,f,_f])

Can't you use the inverter models available in PSSE?

There is a fatal error in the user model (mayby a divistion with zero), leading to the PSSE crash.

It seems like you have no library models, just 5 calls of user models. Do you have the source code?

Are you modeling a system with solar plants without synchronous generation? Is it possible to use that model in a pure solar system?

Try a simple system with one synchronus generator and one (small) solar plant.

When the dynamic run does not initialize, it cannot continue. The problem has to be resolved. It could be a dll created for a different version of PSSe?

Start by opening a log file at the beginning of the run to capture all the verbose as PSSe activities are being called. Check for keywords like "not found" or "not loaded" and post any error messages.
