Hi Gang,
Thanks for your reply. I tried that, and it can work quite well.
Thanks again.

Hi Xian,
For both of your questions, yes!
To model multiple generators connected to the same bus, just create a new
row in "mpc.gen" (note: please do not forget the corresponding row in
"mpc.gencost") and fill it with the data of a new generator. To model
multiple loads, you can add them up to th
Hi,
I have a quick question about the mpc case modelling file.
Could I have multiple generators and loads connecting to the same bus? If
so, how to model this in "mpc.bus", "mpc.gen", "mpc,gencost" matrix? Also,
for the slack bus, if I have both generators and load connected to that,
should th
Hello,
The obj_func mainly minimizes the cost including the real and reactive
power.
But I have to only minimize objective function i.e. cost considering only
the reactive power.
I tried the way explained by you above but I am not able to do this.?
Can you help?
basically, my goal is to change the
Hi,
It's not in the runpf.m file. The function makeJac() is defined in the file
makeJac.m . In the file makeJac.m, the Jacobian matrix of the power mismatch
formulation is calculated and can be called with the command makeJac().
Inside file runpf.m, the functions are only called, not defined. T
ok, thanks

Try to have a look in the code in opf_costfcn.m and compare it with the
objective function definition in the manual
(http://www.pserc.cornell.edu/matpower/manual.pdf) section 6.1 equation (6.6).
You will find the function implemented in the code, as well as its gradient and
Hessian w.r.t. vecto
Can you explain me through simple example.?

Hello,
as far as I know, you can define arbitrary objective function by modifying the
following source file: opf_costfcn.m. Don’t forget that you need to provide
gradient and Hessian w.r.t. OPF control variables as well. These derivations
are used in optimizers to find the optimal solution.
