Steady state stability of a power system is the ability of the power system to

A $$100$$ $$MVA$$, $$11$$ $$kV$$, $$3$$-phase, $$50$$ $$Hz$$, $$8$$-pole synchronous generator has an inertia constant H equal to $$4$$ $$MJ/MVA.$$ The stored energy in the rotor of the generator at synchronous speed will be $$H = {E \over G}$$

During a disturbance on synchronous machine, the rotor swings from A to B before finally settling down to a steady state at a point C on the power angle curve. The speed of the machine during oscillation is synchronous at point(s)

The transient stability of the power system can be effectively improved by
