document: Critical lines identification on voltage collapse analysis This paper deals with critical lines identification on voltage collapse analysis . It is known , from the literature , that voltage collapse is a local phenomenon that spreads around an initial neighborhood Therefore , identifying the system critical bus plays an important role on voltage collapse prevention . For this purpose , the system critical transmission lines should also be identified In this paper , these issues are addressed , yielding reliable results in a short computational time . Tests are done with the help of the IEEE-118 bus and the Southeastern Brazilian systems
