The Optimization on FACTS Devices for Network Security

Abstract

One of the most important indices which are used in FACTS devices placement are indices related to network security and its vulnerability. On this basis, objective function consisting of vulnerability indices of generators, lines and bus bars presented and placement is done simultaneously and nonsimultaneously. For case studies, placement of a UPFC, a TCSC and a SVC in IEEE 30 bus test system are performed simultaneously and non-simultaneously. The results have shown simultaneous placement of these devices improve vulnerability indices more than non-simultaneous placement.
