What I would recommend is making a slight modification to newtonpf.m , where you insert at line 102 a call to a function defined by you, to which you pass the complex bus voltage vector V and anything else you need (e.g.

Any chance this is a duplicate of issue #12 ? If so, it should be fixed in the current version on GitHub. If not, could you please submit a new issue with a minimum working example (MWE) that I can

The model used for the transmission line shown in Figure 3-1 in the User’s Manual. I’m not sure what you mean by the α and β of the transmission line. What do these parameters refer to? Ray > On May 28, 2017, at 10:04 PM, Ameeratul Balqis > wrote: > > Hello

Re: How to indicate in MATPOWER the use of several substations in the cases of radial distribution systems?

2017-05-30 Thread Ray Zimmerman
I’m not sure I understand what you mean by a radial system with more than one substation. You definitely don’t want to set multiple buses of type REF, though you could use type PV for all but one of the substations, but that is equivalent to turning a radial system into a meshed system.

Dear Olaf, I don't agree with your analysis. The results shown by Teiji are deterministic. He made 2 series of 3 runs and the 2 series are identical. Jean >> But, after MATLAB was restarted, the same values of objective >> function can be obtained. >> 1st 8740.2 >> 2nd8731.9 >> 3rd

Dear Jean, I think that Teiji is referring to the problem that if you use the multiple-threaded version of KNITRO you will have different solutions even in the case of using the same initial starting point. Regards, Olaf On 30.05.2017 11:50, MAEGHT Jean wrote: Dear Teiji, Knitro is
