Study of blackout prevention of a power system

The blackout of a power system creates severe inconvenience to its consumers and manyfold losses to the utility. Therefore, the prevention of the blackout is a serious concern of the utility. Auto and adaptive load shedding and islanding are common operational techniques to keep the system stable at a severe perturbation due to faults or loss of generation or switching at bulk loads. This paper investigates the effectiveness and conditions of the use of different blackout prevention techniques with a view to help engineers develop operational strategies of a power system.
