About the research project

This project forms part of the new ARC Industrial Transformation Training Centre for Energy Technologies for Future Grids, a commonwealth funded collaborative initiative between the University of Tasmania and five other major Australian universities, together with fifteen partner organisations from industry. The Training Centre will provide solutions for the problems associated with the transition from fossil-fuel-based and centralised power grids to the renewables-based and decentralised grids of the future. The successful applicant for this project will be provided with opportunities to work as part of the broader training centre team, will work on problems of immediate relevance to industry and will have direct links to and be supported by industry partners.

As high grid penetration of renewable energy (RE) sources reduces system inertia, leading to potential instability, this research project will explore how to handle the generator coherency appropriately during the fault events. Intentional Controlled Islanding (ICI) involves splitting a power system into several self-healing islands as the last protective solution to avoid blackout after a large disturbance. ICI can help limit cascading fault events and avoid wide-area blackouts. Identification of coherent generators (CGs) is necessary for the area-based monitoring and protection system of a wide-area power system and will be investigated in this project. Synchrophasors have enabled smarter monitoring and control measures to be devised; hence, measurement-based methodologies can be implemented in online applications to identify the CGs. As a next step, sophisticated controlled islanding can be designed, which can help to limit cascaded outage. Finding the separation boundaries and stabilising the created islands are two aspects of the ICI problem that will be investigated.
