Hi
Thank you Abhyanker for your input, the example in the manual worked.
I am really new to Matpower and I am learning it from scratch. My intention
is to get the critical value of power and voltage values(Nose point of the
PV curve) of a particular bus, Can anyone please tell me is it possible to
get the values using Matpower using continuation power flow ?
I am trying to modify the example code from the manual (I am working on
IEEE 39 bus system)
define_constants;
mpopt = mpoption('out.all',0,'verbose',2);
mpopt = mpoption('cpf.stop_at','nose','cpf.step',0.2);
mpopt = mpoption(mpopt,'cpf.plot.level',2);
mpcb = loadcase('case39'); % load base case
mpct = mpcb; % set up target case with
mpct.gen(:, [PG QG]) = mpcb.gen(:, [PG QG])*2.5
mpct.bus(:,[PD QG]) = mpcb.bus(:,[PD QG])*2.5
results = runcpf(mpcb, mpct, mpopt);
results.cpf
Thanking in advance
Regards
Nair
