But that's not what I see as controversial...
Take a look at the first 60?+ of the first cycle...
It seems to me that only the PV system can supply the reactive current until just after 60?. During the same timeframe, the service current is outgoing.
At 30 degrees I have:
I_load_real = 66.14
I_load_reactive = 18.49
I_Load = 84.63
I_Gen_real = -122.48
I_Svc = -37.85
So take it home for me as I'm too distracted with other stuff to follow where you are headed.
