This project intends to identify and analyse the structural vulnerabilities of the emerging ‘smart grid’ for electricity supply. The smart grid integrates a cyber network into the existing power network. Although the smart grid enables the integration of more renewable energy sources and contributes to an environmentally sustainable society, the network structure can introduce new vulnerabilities that may cause large cascading failures and lead to catastrophic blackouts. The project aims to establish a quantitative framework to analyse smart grid structural vulnerability. Furthermore, innovative reinforcement and defence strategies will be proposed that could reduce the risk of large blackout and build a more robust smart grid.Read moreRead less
Cyber-Physical Security Analyses and Enhancing the Resilience of Smart Grid. The electrical power industry in Australia is undergoing a massive revolution to an intelligent, low-carbon and sustainable smart grid environment.

The electrical power industry in Australia is undergoing a massive revolution to an intelligent, low-carbon and sustainable smart grid environment. However, due to the heavy reliance on cyber infrastructure and the intermittence of renewables, smart grid will inevitably introduce new security issues, for example, cyber security. This project is to investigate emerging security issues together in a comprehensive framework where quantitative models and analysis methods will be explored for smart grid cascading failure analyses. Then innovative three-stage reinforcement strategies (three lines of defence) will be developed to enhance the resilience of smart grid against natural disasters and intentional attacks, and potential large blackouts.

Producing optimally short pulses at long wavelengths. This project aims to make the fluoride glass fibre platform the preferred material for generating ultrashort pulses at 2.8 nm and beyond. High power and efficiency from simple device architectures are essential for industry, medicine and defence.

This project aims to make the fluoride glass fibre platform the preferred material for generating ultrashort pulses at 2.8 nm and beyond. High power and efficiency from simple device architectures are essential for industry, medicine and defence. Modern sources of short pulses of light emitting mid-infrared wavelengths are complicated and inefficient. This project will improve fibre sources emitting short pulses and create the essential building blocks for future all-fibre arrangements that will be more robust. The sources are expected to have applications in non-linear optics and materials modification.Read moreRead less

When combined with emerging rare earth ion transitions and precise excitation processes, this project will help solve an important problem in optics; that the overall efficiency and power produced from deep mid-infrared light sources is not sufficient for all industries. The primary outcome will be a series of robust fibre-based gain modules suitable for high power and very short optical pulses in the mid-infrared. These light sources will beneficially impact medicine, defence, sensing and manufacturing providing excellent opportunities for increasing Australian productivity and global competitiveness.

Seeing the light: high-power visible-light generation using silicate fibre. Unlike their near-infrared counterparts, visible-light-emitting lasers are inefficient and complicated, impacting their broader deployment in industry, medicine, and telecommunications. To address this, we will create a new class of laser and amplifier based on an entirely new doped silicate glass fibre that will display low background loss and resilience to photodegradation from high-power visible light.

On-chip generation and processing of high-power multi-GHz frequency combs. The project aims to deliver a chip-scale stable optical frequency comb technology with high-power and multi-GHz frequency spacing.

The project aims to deliver a chip-scale stable optical frequency comb technology with high-power and multi-GHz frequency spacing. The lack of this technology has prevented fundamental advances in wide-ranging applications that require high signal-to-noise-ratio (SNR) combs. The project seeks to demonstrate combs using waveguide laser technology and to integrate it with a reconfigurable optical filter to select and process individual comb lines. Key advantages of this technology, including high SNR, reconfigurability, high stability, small footprint and low-cost, are expected to improve astronomy’s ability to detect Earth-like planets, telecommunications to increase the overall internet capacity, and global positioning systems (GPS).Read moreRead less
