Hai ,

This is the answer for displaying the jacobian matrix from the load flow, as
given by Dr Ray Zimmerman, from the previous post. You can try this.
---------------------------------------------------------
The easiest way is probably to set a breakpoint in the Matlab debugger at
line 126 in newtonpf.m, as both Ybus and J (the Jacobian) are sitting right
there and can be viewed or saved or whatever. For example,

>> dbstop 126 newtonpf
>> runpf('case4gs')
126         converged = 1;
K>> full(Ybus)

ans =

  8.9852 -44.8360i  -3.8156 +19.0781i  -5.1696 +25.8478i        0
 -3.8156 +19.0781i   8.9852 -44.8360i        0            -5.1696 +25.8478i
 -5.1696 +25.8478i        0             8.1933 -40.8638i  -3.0237 +15.1185i
       0            -5.1696 +25.8478i  -3.0237 +15.1185i   8.1933 -40.8638i

K>> full(J)

ans =

  41.1963  -26.1026  -15.0938   -4.1183   -2.1655
 -25.6508   44.3270         0    7.0969         0
 -14.7398         0   39.6096         0    5.8755
   6.3048  -10.3721         0   42.9755         0
   3.8683         0   -9.6932         0   38.3186

K>> save mymatrices Ybus J
K>> dbcont

Newton's method power flow converged in 3 iterations.
