Sir,
At nose point in P-V curve using cpf, Jacobian matrix becomes singular.
i.e. determinant of Jacobian to be zero.I am getting very high negative value
of determinant of jacobian at nose point. I have used following
code: define_constants; mpopt =
mpoption('out.all',0,'verbose',2,'out.bus',1); mpopt =
mpoption(mpopt,'cpf.stop_at','nose','cpf.step',0.03); mpopt =
mpoption(mpopt,'cpf.plot.bus',7,'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])*1.35 mpct.bus(:,[PD
QD]) = mpcb.bus(:,[PD QD])*1.35 results = runcpf(mpcb, mpct,
mpopt); J=makeJac(results)
%%% determinant of J det(J)
ans =
-1.0471e+126
Could
you please suggest me what necessary steps I should follow to get determinant
zero?
Thanking you.
