It seems to me that you have an
instance of a data file which is aimed at detailed modeling of all
of the system's elements. This kind of data is useful for
graphical representation, but it poses a major problem: it
assigns different bus numbers to elements that
Dear All,
Of many papers,we read generators in network may cause bi-directional
power flow.My question is that how this bi-directional flow (if exists
after runpf) could be perceived in Matpower?
Thanks
Dear Dr. Ray Zimmerman
I have downloaded matpower4.1 and placed it in the path of matlab, but when I
have typed test_matpower to run the test suite and verify that MATPOWER is
properly installed and functioning, I have got the below message:
test_matpower

Hi LarryHo,
I'm not familiar with OPF in Matpower, so frankly I cannot understand your new
objective function f(x) + fu(x; z). But what I want to comment is, if you want
to get the critical point by nonlinear optimization, you shouldn't include the
conditions of Jacobian and Hessian Matrix as
