Power System Stability

Voltage stability is the ability of a power system to maintain steady acceptable voltages at all buses in the system under normal operating conditions and after being subjected to a disturbance. A system is voltage stable if V Q sensitivity is positive for every bus. A system is voltage unstable if V Q sensitivity is negative for at least one bus.
