If you are purely after rotor angle stability then monitoring angle spread would probably be your best option, which corresponds to your (1). The easiest way to approach this would be using the SYSANG model .
Alternatively, you can use the following criterion: relative angle swing of every machine <= 160-180 deg.

Alternatively, you can may also make use the following criterion: relative angle swing of every machine <= 160-180 deg.OSSCAN model (monitoring only), which scans for out-of-step conditions. However you would need to parse PSS/E progress printing for out-of-step messages.
