   Abstract : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. READ MORE

5. 3. Control of Energy Storage Equipped Shunt-connected Converter for Electric Power System Stability Enhancement

   Author : Mebtu Bihonegn Beza; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transient stability.; energy storage; recursive least square RLS ; electromechanical oscillation; Signal estimation technique; static synchronous compensator; power oscillation damping POD ;

   Abstract : Flexible AC Transmission System (FACTS) controllers, 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 FACTS controllers family, the Static Synchronous Compensator (STATCOM) is a key device for the reinforcement of the stability in an AC power system. READ MORE
