Dear Ray Zimmerman,
Thank you so much sir. I downloaded the zip file from
https://github.com/MATPOWER/matpower/ and installed by followng README
instructions and it was successfully verified with *test_matpower*
instruction. After that I used radial_pf(mpc,mpopt) that gave results for *case
18*, and *case 22* but when I used case33bw it shows errors saying: Error
using radial_pf (line 34)
radial_pf: power flow algorithm PQSUM can only handle radial networks.
Another thing sir, I look for *"Radial Power Flow"* section at *4.1.1 in
Matpower Manual*. May be it still not included. I used the following
command for case33bw:
>> mpopt=mpoption('pf.alg','PQSUM','pf.tol',1e-4,'out.all', 0,'verbose',0);
>> mpc=loadcase(case33bw);
>> results=radial_pf(mpc,mpopt);
>> sum(real(get_losses(results)))
I also tried with "ISUM", "YSUM" but saying the same thing as:
Error using radial_pf (line 34)
radial_pf: power flow algorithm PQSUM can only handle radial networks.
Please sir, Guide me. Thanks in advance for both of you.
Sincerely Yours
