I think in general is a good suggestion for having in the next version. In any
case thanks for the help and your time and many many thanks for distributing
this great tool.

tween the 2 colums (e.g. Pg and Pmax) after every run? Alternatively,
maybe you have a more efficient way to do that?

Hallo Basem,
I guess, except if it's already somewhere else calculated, you can just grab
the abs(mpc.branch(:,14)) (power injected at one end)and divide by the
mpc.branch(:,6) (rating A). I
Fot the losses just calculate the current and multiply it by the losses and

Dear all,
I have the following issue when I'm implementing an OPF I would like to ask if
anyone has experienced ever something similar.
Well, I want to check feasibility for constrained and unconstrained OPF's. When
I have only the max limits of Gens on, the opf solves and the same happens when
Hallo all,
Could please someone confirm that assigning piecewise linear generating costs
(in my case just linear) like below is wrong?

Dear all,
is there a way to make the suc value return 1 only and only if no violation of
any constraint occurs?
Thanks in advance,

I'm not sure I understand what you are changing between the feasible case and
the infeasible one. But if it is infeasible, then it will not solve
successfully, and any results (generation levels, line flows, etc.) are
meaningless.

Dear all,
I would like if possible some feedback on whether I'm following a correct
approach towards changing the dc-opf objective function.
Well, the idea is that I want to include except of the operational costs of the
DC-OPF, curtailment costs for my 3 wind units, penalty costs for infeasibi

Dear all,
just a question to clear something out.
All the pu branch impedances refer to the system Sb and not to the specific
branch's power, right?
Thanks a lot,

Dear Ray,
while trying to find a way to add a user defined constraint I came across this
example posted by you a couple years ago:
What I want to do is to create an equality constraint that will allow only
above a limit of operation of certain units. In fact, I have 14 gens of which
11 are conve
