Below is the 2-bus system that we will concentrate on. This simplified system consists of a generator, load, transmission line, and associated buses.

What follows is a schematic representation of the transmission line between the 2 buses of the above 2-bus system.

Where:

• V₁ represents the voltage at the generator bus.
• V₂ represents the voltage at the load bus.
• The capacitors, inductors, and resistors represent the electrical characteristics of the transmission line.
