Abstract :
Undervoltage load shedding is an economical solution (or partial solution) to the voltage stability challenges facing electric utilities. Simulations for an equivalent system and for large-scale representation of the Puget Sound (Seattle) area of the Pacific northwest led to several concepts for an undervoltage load-shedding program. Application factors such as undervoltage relay settings and time delay are discussed. Pacific northwest utilities are implementing undervoltage load shedding for the 1991-2 winter operation period
