Thank you so much sir. My next question would be, is it possible to compute the 
bus and branch tables from the 54-by-54 admittance matrix? Thank you

When you simplified away the PQ buses, you lost the ability to specify loads in 
them.  So, theoretically, you could perform a load flow in which you can only 
have loads at the 54 generator buses.  You cannot use runpf, though,  as runpf 
starts by building the Ybus matrix from the bus and branch tables; it does not 
take Ybus as an input.  You would have to call newtonpf.m directly with 
suitable parameters.

Hi MATPOWER community,

I asked a question earlier and would like to modify it. I have a reduced 
54-by-54 admittance matrix for case118. Can I use this as an input in MATPOWER 
for my power flow analysis? How do I go about it?
I would appreciate your help. Thank you.
