Series FACTS controllers for power oscillations damping of power system

Power system is subjected to oscillations due to various disturbances that occur in the network. There are various techniques that can improve the power oscillations damping occurring in the network and hence improves the performance of the system. One method which is new and very much effective is the use of static series FACTS controller which are basically combination of power electronic components. FACTS devices are intended to enhance the power system reliability, power transfer capability, stability improvement (both transient and dynamic), congestion management etc. In series compensation, line impedance is modified (decreased), thus increasing the transmittable active power for the network under the uncertain conditions. The paper presents an immense review on the research and development in the area of robust control of power system using series FACTS devices. FACTS controllers and issues related to them are discussed. Paper also includes the application of Series FACTS devices to different Power system area.
