Chech the link. I complited it and also did fast decoupled power flow, Q limits cotrol by using Newton Raphson and using Crout's method.

this is the data file. you just try it for powerflow solution...

Check out the link I send I completed it.
I used Newton Raphson to get it to converge and also used fast decoupled power flow analysis and Q limit control.
Let me know if you have questions.
Good luck!!
