FACTS solutions for voltage stability problems in a large metropolitan area

The purpose of this paper is to apply and assess the performance of FACTS controllers for dynamic voltage support: Dynamic VAR (D-VAR/spl trade/) and advanced static compensator (STATCOM), in a large metropolitan area. To determine the heat location for these controllers, modal analysis and time-domain simulations are used. A good correlation was found between the two techniques. Performance is discussed with only D-VAR/spl trade/ in place, only STATCOM's in place, and a combination of the two.
