Hi! I'm trying to study transient stability our islanded power plant and I came across at some problems.
Firstly, I couldn't find any technical papers about transient stability of islanded microgrids. Can you recommend me something?
Secondly, I have islanded power station, which consists from 8 identical GTG. Each GTG works through transformer to bus 110 kV. At work conditions each GTG works with equal value of active and reactive powers.
I use ETAP and module of transient stability to these studies. For example, when I consider of fault at bus 110 kV, I got this picture and see, that each GTG has the same results as others. It's correct? Can I accept that all 8 GTGs are the same like one big GTG?
Firdly, generator relative power angl has a little deviation in all cases. Can I make a conclusion that each generator is stable?
But generator absolute power angle makes me doubt. What does it means?
