Slack bus - Wikipedia

★ ★ ★ ★ ☆

In order for the variations in real and reactive powers of the slack bus to be a small percentage of its generating capacity during the solution process, the bus connected to the largest generating station is normally selected as the slack bus. The slack bus is crucial to a load flow problem since it will account for transmission line losses.
