I. Introduction:

\(\bullet\) This simple 3 Bus Test Case is taken from the text book of Murty [1].
\(\bullet\) It consists of 3 buses, 3 lines, 2 generators and 2 loads; where bus 1 is considered as a slack bus.
\(\bullet\) For bus 2, the voltage is maintaned at \(V_2=1.03 \ \text{p.u.}\), and the side constraint of the reactive power is set as \(0 \ \text{Mvar} \leq Q_2 \leq 35 \ \text{Mvar}\).
\(\bullet\) Impedances and line charging data:

\(\bullet\) Scheduled generations and loads and assumed bus voltages:

\(\bullet\) Nodal admittance matrix:
