Dear Bela, As far as I know the *UCTE_2002_Summer.m *model* *was made just for DC analysis.
if you see in the model, in the branch data part, the components of the line "r" and "b" are equal to zero. I think, that is the reason why the model did not converge in AC analysis. You have to complete the models for AC analysis, "r" and "b" must have some value. You can try to find if there are a simple rule to set these values as a proportional part of "x" in the line. If anyone on the list know how to complete the model, would be helpful. Bela, If you get a reliable model UTCE network, I invite you to share in the list. For me it would be very useful Best regards, Álvaro Jaramillo Duque On Thu, Sep 20, 2012 at 4:49 PM, Bela Genge <[email protected]>wrote: > Dear Carlos, > > Thank you for the response.
