Under-frequency load shedding and generator tripping are traditional methods used to stabilise a network when a transient fault occurs. These methods will prevent any network instability by shedding load or tripping the most critical gener-ator at a calculated time when required. By execut-ing these methods, the network can be stabilised in terms of balancing the generation and the load of a power system. A hybrid control scheme is proposed where the traditional methods are combined to re-duce the stress levels exerted on the network and to minimise the load to be shed.enThe Research Energy Centre of the University of Cape TownTransient disturbancesCentre of inertia (COI)-referred frame indexPower system stabilityArticle
