And the last question is [how to use Transformers in MATPOWER?]
If there is any explanation related to the above question, could
you provide me the explanations?

Thanks a lot Dr.Ray,
Indeed, i made a printing mistake while i was writing an email, the
meaning of [reluctance] is (reactance*) is referring to branch reactance.
But the one thing that i would know is , when i change the values of
reactance what i will get, Do i have to implement the same code?
Hello,
I am trying to solve an OPF problem where all the PV nodes are fixed to a
certain power and voltage by an equality constraints, and only the slack
bus is left free.
The power consumed by the loads (including losses) is more than the fixed
values of the generators but less than the total pow
I’m not sure what you mean by “reluctance voltage” and “reactance voltage”, but
if you are referring to the branch reactance, then setting it to zero causes
the Ybus matrix to become singular and the power flow fails. See the example
below.

Since the OPF solver expects a minimization problem, and runmarket() wants to
maximize welfare it sets up the OPF problem to minimize the negative of the
social welfare. So, it is the negative of the objective function that is equal
to the social welfare.

Dear all
I am Master student and a new in MATPOWER, using Matpower to find the
losses in transmission lines (runpf) and how to change the reluctance
voltage value in case14 as an example.
Also, to find the daily PV load profile.
Could you please help in writing Matlab code that change the reacta
