Abstract :
[en] After reviewing the basic voltage instability mechanisms, this chapter de-scribes emergency measures that can be used in order to contain voltage insta-bility and prevent a voltage collapse leading to a blackout. A real case of such a voltage collapse in the Hellenic system is presented and analyzed. Emer-gency measures presented include existing or projected controls acting on bulk power delivery transformer load tap changers, as well as direct load shedding. An actual design and application of a load shedding controller in the Hydro-Québec system is presented.
