Thyristor Controlled Series Capacitor as an Optimizer in an Electrical Market

This paper presents an overview over different areas where FACTS devices can improve transmission system efficiency especially under the condition of liberalized electricity markets. Furthermore, a network example, is shown where the installation of Thyristor Controlled Series Capacitor (TCSC) increases the transfer capacity into a region considerably while maintaining security margins. This can help to reduce or even eliminate congestion in a transmission network.
