"For planning purposes, it is important to know the power transfer capacity of transmission lines to meet anticipated load demand" (MOHAN, N. Electrical power systems: introductory course. Editora LTC, 2016, p. 76).
The Newton-Raphson method is a very efficient numerical method for calculating power flow. The following figure shows an electrical power system represented by 3 bars, where bar 1 is reference “Vθ” and the other two bars (2 and 3) are type “PQ”.
