Dear all, I have run the radial bus system using Newton Raphson in Matpower 6.0. And when I run the program the result is like this
MATPOWER Version 6.0, 16-Dec-2016 -- AC Power Flow (Newton)
Newton's method power flow did not converge in 10 iterations.
>>>>> Did NOT converge (0.02 seconds) <<<<<

Of course this is totally wrong because it doesn't match with the single
line diagram. Please help me to finish my final project. I really
appreciate any kind of help. Here I attach my program files.
