Hi Iman, That formulation just said Ploss = sum(I^2*R) = sum(((V1-V2)^2/Z)*R)

(branch(:, BR_R) - 1j * branch(:, BR_X)); As I am not very good at reading codes , is this the same as Pl=Summation Summation [(alpha* Pi*Pj+QiQj)+beta(QiPj-PiQj)] If it is not ,from where the concept of losses has been taken?Does any one know please? to see the formula in a better format see the attachment -- Best regards Iman -- Best regards Iman
