11/24/2017 · The slack bus (aka swing bus) is the only bus in a power system that can compensate for both real power (P) and reactive power (Q). PQ buses have fixed P and Q and PV buses have fixed P and V (voltage magnitude). A slack bus may be called a “slack” bus because it picks up the P and Q slack the other buses fail to provide to the system.
