| dc.description.abstract | Over the past 30 years, a device known as a Distributed Superconducting Magnetic Energy Storage (D-SMES) has been under development and proposed to solve various grid performance challenges. A D-SMES is device with a shunt reactive power injection/voltage support with real power component. The use of a D-SMES is considered as a new option at experimental stages to solve plenty of transmission, generation, and distribution system problems, including improvement of voltage and angular stability, increasing power transfer capability, damping oscillation including smart grid. The purpose of this dissertation was to demonstrate how D-SMES can alleviate voltage instability in a network. The study gives an overview of the D-SMES applications, its characteristics and classification. Two case studies, namely; an IEEE network and a real Southern Africa network are studied with voltage instability under contingency condition. The process flow is proposed and presented using modal analysis as a tool to identify the optimal location in a network to mitigate voltage instability. The results of the two case studies demonstrated improvement in the voltage instability of the respective networks. Modal analysis proved to be an effective method to identify the optimal location of a SMES to improve voltage stability. The findings of this dissertation are in line with the literature. | en_US |
