Thank you for you interpretation Prof Ray. Actually I have found a
function called sgvm_add_shunts() in matpower -> extras ->syngrid,
which looks like it may do what I want, but I am not sure because there
is not too much annotation in its source code and user's manual.

integrated interface like runpf() and runopf() to implement mixed integer
programming using other solvers. There is still quite a lot for me to learn.

Thank you for your suggestion Prof Ray. Actually I am still learning about the
mechanism of uopf() and I dont really understand what binding Pmin limits
means. In the attached files, if the cases with and without shunt generators
have the same limits of voltage magnitude, the case with shunt gen
Thank you amini, but I dont really learn much about PSO. Do you mean partical
swarm optimization? I think I need more time to learn about it.

That is also a good idea and closer to reality because shunt capacitors and
reactors will actually change the Ybus instead of performing as constant
reactive power. But I dont know how to include the 6th column of bus as a
variable and modify the objective function. Would you please share your c

Dear Alireza SalimAmini
Thank you for your care and blessing. I think I have implemented this using
runuopf(), a built-in function of matpower to do mixed unit commitment and OPF.
In such cases where geneators are used to model shunt capacitors and reactors,
just add a few generators whose rea
hi
i wish u are healthy at this conditions( Covid19)
i think if you adjust Qmin and Qmax of capacitors at 'gen' matrix equal to
6Mvar, it will help , and you can use status ( it is a column in gen matrix
as came below) of that capacitor a variable for reactive power balance.

Dear all,
I am working on optimal power flow whose objective is the cost of generation
plus the quadratic deviation of voltage magnitudes to 1.0. The special
part of the optimization lies in it that it has to include shunt capacitors and
reactors in this network apart from conventional generato
