A high performance, robust and sensorless Natural Field Oriented controller for induction machine drives. Natural Field Orientation (NFO) is a technique of field oriented control of AC machines that is potentially very robust, able to operate at low speeds, and inherently sensorless. However, it is a little known fact that under regenerative conditions the algorithm is unstable. The primary aim of this project is to develop a NFO algorithm that is stable under regeneration, and has minimum depen ....A high performance, robust and sensorless Natural Field Oriented controller for induction machine drives. Natural Field Orientation (NFO) is a technique of field oriented control of AC machines that is potentially very robust, able to operate at low speeds, and inherently sensorless. However, it is a little known fact that under regenerative conditions the algorithm is unstable. The primary aim of this project is to develop a NFO algorithm that is stable under regeneration, and has minimum dependence on machine parameters. If these aims are achieved the NFO algorithm would be a significant addition to control algorithms for AC machines, allowing their use in a broader range of applications.

Multilevel converters. Until recently the vast majority of power electronic applications have been to low voltage systems. However, developments in high voltage semiconductor switches in the last decade have generated significant activity in high voltage power electronic applications.
Traditional two level converters have significant problems in high voltage applications - high output dv/dt damages insulation and motor bearings, and the semiconductor switches have high switching losses.

Traditional two level converters have significant problems in high voltage applications - high output dv/dt damages insulation and motor bearings, and the semiconductor switches have high switching losses.
Multilevel converters hold the promise of alleviating these problems. This project will research and develop multilevel converter technology for static VAR compensators and medium voltage drives, initially targeted at mining applications.Read moreRead less
Understanding participant behaviour in wholesale electricity markets. Wholesale electricity spot markets now operate in many countries including Australia. The aim of this research project is to achieve a better understanding of the operation of electricity markets, through advancing our understanding of how the physical system, the industry structure, the market mechanism and the behaviour of the market participants jointly determine the overall system outcomes.

The aim of this research project is to achieve a better understanding of the operation of electricity markets, through advancing our understanding of how the physical system, the industry structure, the market mechanism and the behaviour of the market participants jointly determine the overall system outcomes. A particular focus of the research is on competition within the market. We want to understand the ways in which market structure influences participant behaviour and, in particular, the circumstances that lead to non-competitive outcomes.Read moreRead less
Understanding the interactions between emissions trading and wholesale electricity markets. Australia faces some critical decisions with regard to its commitment to reducing emissions of greenhouse gases. There are a variety of emissions-related trading schemes that operate at a State level, and there are now proposals to introduce a National scheme.

Australia faces some critical decisions with regard to its commitment to reducing emissions of greenhouse gases. There are a variety of emissions-related trading schemes that operate at a State level, and there are now proposals to introduce a National scheme. This research will help in the design of an emissions trading scheme through the use of sophisticated models of the behaviour of individual generation companies operating in a complex market situation. Also this project will build the skill base of Australia in an area of increasing importance where a multi-disciplinary focus is critical.Read moreRead less
Design, build and test a fault current limiter employing magnesium diboride (MgB2) superconducting coils. Recent occurrences of blackouts around the world caused immeasurable damage to electrical network hardware in the range of $10M, however, the losses from an unavailable network are much more. The CIs and Zenergy Power Pty Ltd (formerly Australian Superconductors) have been developing saturated core fault current limiters (FCL) since 1999. The first saturated core fault current limiter employ ....Design, build and test a fault current limiter employing magnesium diboride (MgB2) superconducting coils. Recent occurrences of blackouts around the world caused immeasurable damage to electrical network hardware in the range of $10M, however, the losses from an unavailable network are much more. The CIs and Zenergy Power Pty Ltd (formerly Australian Superconductors) have been developing saturated core fault current limiters (FCL) since 1999. The first saturated core fault current limiter employing the Australian's entity's technology was installed in California. The aim of this proposal is to extend this technology to demonstrate next generation FCL using a newly developed superconductor magnesium diboride (MgB2) wire which is cheaper and easier to manufacture than high temperature superconductors and the CIs' group hold strong IP on nano-scale chemically doped MgB2 wires.Read moreRead less

Breaking Performance Limits of Solar Inverters for a Sustainable Future. Micro-inverters offer a unique ability to maximise solar energy yield and streamline the installation, operation and maintenance process of solar power generation, thus having huge potentials to drastically reduce the cost of solar electricity.

Micro-inverters offer a unique ability to maximise solar energy yield and streamline the installation, operation and maintenance process of solar power generation, thus having huge potentials to drastically reduce the cost of solar electricity. However, performance limits have hampered their wider applications in the energy sector. This project aims to tackle the performance challenges of micro-inverters by developing a novel power-conversion architecture, a unified design framework, and a new control theory. The intended research outcome will be a new range of ultra-high-performance micro-inverters. This will promote greater solar uptake and maintain Australia’s leadership in the development of disruptive solar power generation technology.Read moreRead less
