Power System Security
•It is the ability of the system to withstand credible
contingencies without violating the normal operating
limits.
• Classified as
Static security
static security evaluation detects any potential
overload of a system branch or an out of limit voltage following a
given list of contingencies
Transient security
transient security evaluation pertains to system
dynamic behaviour in terms of rotor angle stability when
subjected to perturbations
