    5. 10/15/2011 EE532 Lecture 1 (Ranade) 5 Power System Stability Definition (Ch.2) The ability of a power system to reach a new steady state or equilibrium after a disturbance. Interconnected synchronous generators must settle to a common, constant speed Voltages and power flow must settle to reasonable values ( otherwise relays will trip breakers)
