Abstract

The objective of this chapter is to provide a classification of the basic loss of stability mechanisms relevant to voltage phenomena and to point out appropriate countermeasures. In the previous chapter we have seen that a gradual parameter variation may result in a loss of stability through a saddle-node bifurcation. However, in many voltage incidents experienced so far, instability occurred following large disturbances, such as short-circuits, line outages, or generator trippings. The emphasis in this chapter is on instability mechanisms induced by abrupt, large variations in the structure and/or the parameters of the system.
