Hi MATPOWER users, I'm comparing the results from the function get_losses() and the equations Ploss = Pkm+Pmk and Qloss = Qkm+Qmk. A difference in the reactive power losses is intriguing me.
Taking the IEEE 14 Bus Test System, these are the results I obtained for branch 1-2: - get_losses(): Ploss = 4.29760033602037 p.u.; Qloss = 13.1212080434636 p.u. - Power flow equation*: Ploss = Pkm+Pmk = 4.29760033602037 p.u.; Qloss = Qkm+Qmk = 7.27195804346369 p.u. *The code I implemented to compute the losses are: Ploss(:,i) = resultado_fp.branch(:,14)+resultado_fp.branch(:,16) and Qloss(:,i) = resultado_fp.branch(:,15)+resultado_fp.branch(:,17). I'm not understanding why the reactive power losses are different in these approaches. Until now I'm assuming that the differences are related to computing the losses as functions of bus voltages in get_losses(). Could anyone help me with this? Best regards, Fábio Donisete Silva
