  7. 5. Power System Stability Enhancement Using Shunt-connected Power Electronic Devices with Active Power Injection Capability

    Author : Mebtu Bihonegn Beza; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power Oscillation Damping POD ; energy storage; Adaptive estimation; Static Synchronous Compensator STATCOM ; Recursive Least Square RLS ; Transient Stability Enhancement TSE ; FACTS; Static Var Compensator SVC ;

    Abstract : Power electronic devices such as Flexible AC Transmission Systems (FACTS), both in shunt and series configuration, are widely used in the power system for power flow control, to increase the loading capability of an existing line and to increase the security of the system by enhancing its transient stability. Among the shunt-connected FACTS controllers family, the Static Synchronous Compensator (STATCOM) and the Static Var Compensator (SVC) are two key devices for reinforcing the stability of the AC power system.
