Question

he node (busbar) and branch (line) data of a power system are provided in
Table Q1.1 and Table Q1.2 respectively. All values in the tables are stated in per
unit (p.u.).

Using node 1 (busbar 1) as the reference (slack bus), calculate the line flows
using the DC power flow method.

F₁ = -0.544 p. u.
F₂ = 1.45 p. u.
F3 = 1.54 p. u.
