POWER SYSTEM STABILITY - College of Engineering and ...

Power system stability involves the study of the dynamics of the power system under disturbances. Power system stability implies that its ability to return to normal or stable operation after having been subjected to some form of disturbances. From the classical point of view power system instability can be seen as loss of
