Question

The quantities to be obtained at slack bus with usual notations are

• A. \(Q,\, \delta\)
• B. \(P,\, |V|\)
• C. \(P,\, Q\)
• D. \(|V|,\, \delta\)

Hint:

Slack bus is used to balance real and reactive power in the system; voltage magnitude and angle are specified.

Answer 1

The Correct Option is D

In power system load flow studies, the slack bus is assigned a fixed magnitude and angle of voltage:
- \(|V|\) (magnitude)
- \(\delta\) (phase angle)
All other quantities are computed.
