Dear Ray,
Regarding your previous email. Could you please explain more detail with
example calculation how to get the values of critical power? Because I am
new for continuation power flow.
Best Regards,
Natakorn Thasnas

Hi Arun,
Please see FAQ #2 http://www.pserc.cornell.edu/matpower/#homework. The LMP
from an OPF solution can be found in the LAM_P column of results.bus (see Table
6-1 in the User’s Manual http://www.pserc.cornell.edu/matpower/manual.pdf).
MATPOWER does not implement any SQP solvers.

Hello,
i have the following test case and i'm trying to find the Jacobian
matrix of NR method using the /makeJac/ function of matpower and a code
that i have implemented in matlab.
However, the results between the two methods, which are attached below,
are different and i think that my code
If you run a continuation power flow in MATPOWER, runcpf(), with the option
'cpf_stop_at' set to NOSE then the CPF will terminate on reaching the nose
point. runcpf() returns a mpc case struct that has details on the generation
and loading at the critical point and the lambda (continuation
Hi Rurizwan,
fmincon is more general than SQP as it supports more general non-linear
functions. Also, fmincon and an SQP solver likely implement very different
algorithms. So in those senesces they are quite different.
On the other hand, if my understanding of the underlying algorithms is
It looks to me like your matrix simply uses a different ordering of the rows
and columns. My ordering places all PV buses before PQ buses for the real power
rows and voltage angle columns, since that’s the way the variables and
mismatches are ordered in newtonpf(). Looks like you have the same
Hi Ray ,
Thanks for the reply.

Currently MATPOWER only handles constant power loads. You could
technically model a constant impedance load as well by putting the
appropriate values in the GS and BS
is fmincon solver equal to SQP solver?

Hi All
I need to analyse the effect of different kinds of load models (like ZIP
load model, composite load model, exponential load model etc ) in IEEE 39
bus system, its for my graduate research.
Is it possible to do it Matpower, or is there any other way to do it?
Your help will be greatly
