Hi all
I am interested to add an objective function to the OPF formulation.
The objective of the function is to minimize the deviation of the
power exchange (active and reactive) between areas in a big power
system, calculation the deviation from the start point.
The main idea is maintain the p
simple example, which
cover the whole procedure of Extending the OPF from beginning to end*?
• de fine and access variable/constraint sets as individual named blocks
• de fine constraints, costs only in terms of variables directly involved
• pre-process input data and/or post-process result data
• pri
I'll start with your last question. The extensible OPF architecture in MATPOWER
supports only linear user constraints. The user cost terms can have a quadratic
form with additional features detailed in section 5.3.1 of the manual.
So, I don't see a way to add the costs you want directly to the c
;.
I also read the chapter 6 "Extending the OPF" and part of the code for the
reserve problem.
That is not clear to me, if it is necessary to code a callback functions to
implement the "user defined cost" described in the section 5.3.1 and 6.1.
Or if I can to define the par
ed cost".

Dear Professor Zimmerman and all members
I still have problems with the "User-defined Cost" function in MATPOWER. In
the end I always got a convergence problem.
First, I want understand the meaning of the all variables. In the equation
(5.27) of the manual, the first term is for the quadratic par
Dear Alvaro,
Ok, I think i see what you're trying to do, but there are a few mistakes. I
assume you are trying to minimize the square of the difference between the
dispatch and a precomputed loss-minimizing dispatch, correct?
So, equation (5.27) does have quadratic and linear terms for w, but i
ers for about one month I can't use them all together yet!

Hi,
I was trying to understand the documentation for extending the OPF in
section 7, when I came across the code for adding reserves on page 86, I
got kind of confused regarding the addition of linear constraints. I have
several questions regarding that,
a. How to define the 'Pg_plus_R&#
I am sorry, please ignore the first two questions.
