Abstract

One of the major causes of voltage instability is the reactive power limit of the system. Improving the systempsilas reactive power handling capacity via flexible AC transmission system (FACTS) devices is a remedy for prevention of voltage instability and hence voltage collapse. In this paper, the effects of four FACTS controllers, SVC, STATCOM, TCSC, and UPFC, on voltage stability will be studied. The IEEE-14 bus system is simulated to test the increasing loadability. With continuation power flow feature of PSAT and accurate model of these controllers, voltage stability of the test system is investigated and bifurcation points are detected.
