Dynamic simulations in power system require good modeling of all the dynamic devices in the network. In particular, a generator unit needs a generator model (GENTPJ is preferred), an exciter model to control reactive output, a governor model to control active power output, a power system stabilizer (PSS) to help damp oscillatory behavior, excitation limiters to limit reactive output, and protection relays (V, F). Other dynamic devices like STATCOM, SVC, might be requires to provide voltage control dynamically. Load dynamic models (composite load models representing motors, AC load, other) will affect the local response (FIDVR events).

Models parameters are set accordingly to the MW size of the units, the generation technology, etc. In PSSe, activities like Erun and Grun will give you an idea how exciters and governor respond to a step test. PSS required a tuning over the 0.2 to 2.0 Hz range.

Once you have sufficient models, a no-disturbance test will help to id those models or network conditions that need adjustment. After you get a good response (= flat lines plots of monitored variables) to the no-disturbance test, you can proceed to apply fault tests.

Search the post "can u send dynamic data for IEEE-24 bus and IEEE-30 bus system" for additional test systems.

Are you simulating steady state or a disturbance? Depending on the disturbance you will also need exciter models and governor models.
