Hi,
The answer below given by Ilias is correct. However, you do not have to
call radial_pf directly. It is better to call it via runpf like this
opt = mpoption('pf.alg', 'PQSUM');
result = runpf('case33bw', opt);
In this case runpf makes all input data preparation and indexing. Before
running any power flow solution method in runpf there is a call to
ext2int which removes all isolated buses, off-line
generators and branches, as well as any generators or branches connected
to isolated buses.
Best regards,
Mirko

Hi Paulo,
Could you please share your network (case69teste1)? Because, I think
it runs for (just) case69.
Thanks, and regards,
Ilias

Dear Ilias,
Thank you very much for your answer to my question.
It was very helpful but I still having some problems with my case
study.
In fact, after run the code you send me, I obtain the following
errors.
Can you, please, help me in understanding the problem?
Thank you again
Paulo

Hi Paulo,
Please see the code below:
mpc = case33bw;
c = mpc.branch(:,11); % 0,1 branch status
mpc2 = mpc;
mpc2.branch = mpc.branch(c~=0,:);
mpopt = mpoption('pf.alg', 'PQSUM');
result = radial_pf(mpc2,mpopt);
I remember that in order to use radial_pf, the network should
be radial, which means that even if there are open branches
which create a loop, they should be removed.
Hope this helps.
Kind regards,
Ilias

Hi,
I have a difficulty in running a radial power flow by
using the radia_pf function in the matpower.
Can you help me in this regard?
Thanks
