Hi every one,
I am trying to solve AC Power flow in matpower. I made my own model in
matpower format and when I run it, it got converged in a few iterations and
gave me the solutions. the problem is the given solution is not correct. I
mean when I calculate the power flow based on given Vmag and Vang the
mismatch is not only zero but also large numbers. I am wondering how it
could happen.
Furthermore when I look at the flow at the branch, losses on the lines are
not equal the difference between S_from and S_to, for example :
Brnch From To From Bus Injection To Bus
Injection Loss (I^2 * Z)
# Bus Bus P (MW Q (MVAr) P (MW) Q
(MVAr) P (MW) Q (MVAr)
16 13 16 -168.57 26.10 168.93
-47.47 0.357 3.82
17 13 19 122.42 -38.42 -122.07
-4.82 0.349 3.64
18 13 21 107.36 -34.03 -107.17
3.36 0.189 1.97
19 16 17 -95.59 -2.66 95.74
-28.46 0.147 1.56
I would really appreciate if you can help me understand why it is so.
Thanks,
Mahraz
