Electrical Engineering QUESTION #2146
Question 1
In Power System Analysis, the Slack Bus is used to:
  • Fix the real and reactive power ($P$ and $Q$)
  • Provide the reference for voltage magnitude $V$ and angle $\delta$✔️
  • Compensate for transmission losses only
  • Monitor the power factor of the grid
Correct Answer Explanation
The Slack (Swing) bus serves as the reference where $V$ and $\delta$ are specified to balance the real and reactive power in the system.
