Voltage stability assessment of a power system incorporating FACTS in equivalent mode

Abstract EN

Two-bus network equivalent is commonly used to get a quick overview on the voltage stability of a multi-bus power system.

This paper presents a method to predict the voltage collapse point of power system incorporating two major FACTS devices i.e., Static VAR Compensator (SVC) and Static Synchronous Compensator (STATCOM) using a two-bus integrated equivalent system.

The proposed methodology has been applied under simulated condition on IEEE 57-bus test system to illustrate its effectiveness using a voltage stability indicator being derived from developed equivalent model.

Voltage stability margin augmentation with the application of SVC and STATCOM is compared with the system having no compensation.
