Predicting environmental extremes in a period of climate change. This project has the potential to reduce the uncertainty in the predictions of extreme winds and waves used to design and operate coastal and offshore facilities.

This project has the potential to reduce the uncertainty in the predictions of extreme winds and waves used to design and operate coastal and offshore facilities. Predictions are typically achieved by extrapolating recorded data to predict probable extremes. The uncertainties associated with this approach are very large. This project aims to develop a new approach called ‘large ensemble aggregate’ analysis, which brings together data from alternative model predictions or alternative measurement locations to expand the effective data and avoid the necessity for statistical extrapolation. This approach may significantly reduce the uncertainty in estimating extreme values. This would reduce the cost of constructing coastal and offshore facilities and decrease the risk of catastrophic failure.Read moreRead less
Stability Analysis of Power System with Massive Power Electronic Devices. The decarbonization of Australia's power systems is to integrate massive renewable energy sources which are interfaced with many power electronic devices (PEDs).

One of the most critical environmental issues facing society is that of global warming because of increasing concentrations of carbon dioxide released from burning of fossil fuels. Storage of CO2 in the ground, geo-sequestration, offers the promise of significant reductions in atmospheric CO2 release, particularly from coal fired power stations which produce 40% of Australia's CO2 emissions. The proposed project will lead to greater understanding and reduced risks during the injection and storage of CO2 in deep unmineable coal deposits. This will contribute to national efforts to reduce global warming, safeguard the Australian coal industry, and allow continued electricity generation from coal-fired plants. Read moreRead less
