The Enhanced Performance SVC for Transient Instability Oscillation Damping

To utilise green energy, renewables have penetrated into utility. However, its intermittent nature affects on power quality and network stability. Static var compensators (SVCs) have been installed in order to gain power quality improvement. Nevertheless, lacking of real power support, the SVCs cannot minimise any instability. This paper presents a technique to provide the SVCs the ability to enhance their performance. Dynamic oscillation damper is co-located with a typical SVC, offering ability to damp oscillations. Simulation shows the proposed system performance was greatly enhanced. This envisages future applications, where a combination of distributed generators and renewables causes severe interaction.
