Error in the direct approach for power flow calculation
I find this question asked by me 2 months ago is very stupid. There is no concept called current loss in such networks or DC networks. Only power is lost along cables, and voltage drops. So the formulation in [teng2003direct] is correct. That formulation can be found in other paper as well, like [conti2006voltage].
