, there isn’t a simple way to do it with only linear constraints.
You could define new variables for the flows and use the opf_branch_flow_fcn()
and opf_branch_flow_hess() functions to implement an equality constraint that
defines these variables. These constraints would be very similar to the

Hello everyone,
I’m trying to solve an AC OPF with extra linear constraints on the line flows.
To be more specific, it is an equality constraint with some linear combination
of the line flows, say $\sum_{e\in E} f_e = constant$.
I read the user manual and found that branch flows are not
Yes, this is possible. And you can use either method to accomplish it, that is
either direct specification or callback functions.

Hello,
Is it possible to add a constraint relation between 2 different entities, like
voltage and reactive power using the add_constraint function? For instance, is
it possible to add this type of constraint 2<= Q(i) - V(i) <= 2?
And if so, is the code the same as in the MATPOWER manual?
Thank y

Dear all,
I have a question regarding the extension of Matpower OPF by user-defined
non-linear constraints.
I implemented some additional non-linear constraints in the matpower code
itself, following pretty much Ray's guidelines from an earlier post found

Dear MATPOWER team,
I am trying to add linear constraints to an OPF with AC and DC lines.
I would like to limit the power flow over the DC lines. I know that
it is pretty simple to implement the constraints by defining an A

No, there is no mathematical reason. It is simply that it is straightforward to
specify general linear constraints as additional data (a matrix and a vector or
two) to a solver. On the other hand, facilitating user-specified general
non-linear constraints typically requires the ability to
Dear all,
im working on a security constrained optimal power flow. At the moment I am
using add_userfunction to add constraints, which include the outage of
generator and branches.
My problem is the adding of non-linear constraints. Because I can only add

It does not converge and gives the error "SMARTMARKET: non-
