AW: Convergence issues: OPF simulation of several interconnected countries

2014-07-17 Thread Eser Patrick
Hi guys, first of all thanks @Roman for your inputs. I have found a way that delivers reliable convergence, but still has a slight weakness: I am using the "Interface Flow Limits" extension. This enables me to define all lines between country A and B as one interface, which gives the code more

Tell me a little more about how you stitched together the different systems. Did you have separate data files for different sections of the system and then you actually interconnected them? What do you mean by "realistic" at this stage? Or did you have one single file with all sections in i

Ray, Carlos, Shri, Thanks for your inputs, I really appreciate your help. With regard to your responses: @Shri: How would I impose the Smin and Smax of the tie-line in the MATPOWER intput? I can't see anything alike in the mpc.branch struct, as PF, QF, PT and QT are ignored as inputs accordi
