Dear Iman, 1、I think Panagis is right. Besides, I have ever thought about whether Matpower could solve asymmetric network. Essentially, Matpower is a linear circuit solver using node voltage-injection equations. So I think it is not impossible to use Matpower to solve an asymmetric system with a complete 3 phases network model. 2、No. Per branch.

The one-line equvalent model is created from a symmetrical system. Therefore, there is no point in positive, negative or zero sequence data. r and x are p.u. Someone working in MATPOWER coding can correct me.
