摘要：Two-bus network equivalent is commonly used to get a quick overview on the voltage stability ofa multi-bus power system. This paper presents a method to predict the voltage collapse point ofpower system incorporating two major FACTS devices i.e., Static VAR Compensator (SVC)and Static Synchronous Compensator (STATCOM) using a two-bus integrated equivalentsystem. The proposed methodology has been applied under simulated condition on IEEE 57-bustest system to illustrate its effectiveness using a voltage stability indicator being derived fromdeveloped equivalent model. Voltage stability margin augmentation with the application of SVCand STATCOM is compared with the system having no compensation.
