1) Assuming you want to run a power flow, you simply set the PG column in the 
gen matrix to the output of the wind generator at the moment you are 
simulating. If you want to solve for different wind conditions and output 
levels, each will be a separate power flow run with a different value of PG in 
the gen matrix..

2) Yes. But the “how" depends on the system and range of operating conditions, 
etc.
