Subject: CPF power flow did not converge

Hi all,

I am trying to analyse the influence of topology changes (like disconnect 
branches) on system voltage stability using the following code:

define_constants;



mpc =loadcase('FourAreaNetwork');   "
OutmailID: 123739424, List: 'matpower-l', MemberID: 83373175
SCRIPT: "load basecase
mac.branch(:,11)=[0,0,1,0,1,1,1,1,1,1];"
TCL MERGE ERROR ( 07/11/2019 13:54:03 ): "invalid command name 
"0,0,1,0,1,1,1,1,1,1"change branch status

mpopt = mpoption('out.all',0,'verbose',2,'out.bus',1);
mpopt=mpoption(mpopt,'cpf.stop_at','NOSE','cpf.step',0.05);
mpct = mpc;  "
OutmailID: 123739424, List: 'matpower-l', MemberID: 83373175
SCRIPT: "set up target case with basecase
mpct.gen(:,[PG QG]) = mpc.gen(:,[PG QG])*2
mpct.bus(:,[PD QD]) = mpc.bus(:,[PD QD])*2
results = runcpf(mpc, mpct,mpopt);
After running this, I got the warning message ‘ CPF TERMINATION: Base case 
power flow did not converge.’
Then I decreased the size of cpf step, but still got the same warning.
Could you please suggest me how should I fix it? And I have attached the 
FourAreaNetwork case file.
Thanks in advance!
Best regards,
Cynthia
