Effects of FACTS Devices on a Power System Which Includes a Large Wind Farm

Nowadays, power systems are facing new challenges, such as increasing penetration of renewable energy sources, in particular wind generation, growing demands, limited resources, and competitive electricity markets. Under these conditions, the power systems has had to confront some major operating problems in voltage regulation, power flow control, transient stability, and damping of power oscillations, etc. Flexible AC transmission system (FACTS) devices can be a solution to these problems. This paper investigates the application of FACTS devices on a 12-bus multimachine benchmark power system including a large wind farm. A STATCOM and an SSSC are added to this power network to provide dynamic voltage control for the wind farm, dynamic power flow control for the transmission lines, relieve transmission congestion and improve power oscillation damping and transient stability
