Summary
Accurate Fault Location Methods for Complex Power Networks. This project aims to devise novel algorithms to tackle one of the longstanding and challenging problems in power networks; finding the fault location in power lines. Recent bushfire preventive technologies that have been installed in power networks make the fault location process extremely challenging and time-consuming, leaving communities without power for many hours in extreme heatwave conditions.

This project aims to devise novel algorithms to tackle one of the longstanding and challenging problems in power networks; finding the fault location in power lines. Recent bushfire preventive technologies that have been installed in power networks make the fault location process extremely challenging and time-consuming, leaving communities without power for many hours in extreme heatwave conditions.
The intended outcomes of the project are innovative algorithms that are able to pinpoint the fault location more accurately in complex networks, with many fewer measurement devices than conventional methods. This is expected to provide significant benefits for public safety and power supply reliability.Read moreRead less

This project aims to quantify technical margins and devise novel robust renewables hosting capacity enhancement methods for active distribution networks. High renewables penetration has impaired power quality and network operational reliability, thus reducing renewables utilisation rate and impeding further installation. The intended outcomes are innovative data-driven robustness design methods against complex and uncertain operating conditions, which are able to secure increasing renewables penetration and installation. With emerging community battery and hydrogen electrolyser, a suite of operation and planning methods will be developed, allowing utility operators and government agencies to expedite zero-emission energy transition.Read moreRead less
Regulation of the Cell Bus Voltages of Large Scale Modular Multilevel Converters: Advanced Energy Converters for Future Electricity Grids. Large scale power electronic converters are essential to the emerging “Smart Grid” electrical distribution networks, using large numbers of cascaded cells to operate at the very high voltages that are required for direct grid connection.

Large scale power electronic converters are essential to the emerging “Smart Grid” electrical distribution networks, using large numbers of cascaded cells to operate at the very high voltages that are required for direct grid connection. At present, the fundamental factors that drive the fluctuations of the cell DC link voltages, including in particular the complex non-linear interactions caused by the physical cell switching processes, are very poorly understood. This project will use a new harmonic analysis strategy to investigate the basic engineering science that underpins this voltage fluctuation phenomena, to achieve a quantum step in the understanding of the fundamental operating processes of large scale cascaded converters.Read moreRead less

Compact reliable fault-tolerant modular high power converters. This project aims to deliver new and advanced converter hardware and control designs with drastically smaller reactive components that are cheaper to convert, more reliable and compact. Voltage and current-sourced modular multilevel converters have delivered the required voltage/current/power ratings for utility applications such as static compensators and high-voltage direct current transmission. However, these energy storage components, including embedded batteries, are overwhelmingly large. Anticipated outcomes are that compact, cheaper and even more efficient power electronic energy converters will enable much needed sustainable energy grids; reduce the cost of integrating renewable energy generation in the grid and achieve even more efficient electronic control of electric systems.Read moreRead less

The main aim of this project is to deliver appropriate frequency standardisation to protect electricity grids and support the use of renewable energy sources. Globally, there is no harmonic standardisation within the frequency range of 2–150 kHz, which can significantly affect the reliability of electricity networks and smart grids. Electricity networks are increasingly using renewable energy sources and an efficient loads approach based on power electronics technology. However, this can affect grid reliability and robustness. The project aims to develop advanced tools to better understand the power quality issues of Australian residential, commercial and industrial distribution networks. It also aims to develop novel techniques to improve power quality and reliability of the grids, and to develop harmonics emission and immunity levels to modify the Australian standards accordingly.Read moreRead less
