Electrical power grid is most complex and densely interconnected, which increase instability when power is transferred through transmission lines for long distances. Historical data and blackouts analysis shows the importance of power system stability. This paper discusses power system stability such as rotor angle stability, transient stability, frequency stability and voltage stability. There are FACTs devices like TCSC & SVC, breaking resistor and fault current limiters may be used to enhance transient stability. Moreover, fast fault clearing and auto reclosing techniques can be designed to enhance power system stability. AVR & PSS with governor helps to damp out oscillation after fault clearance.
