better market operation and management following recent devastating blackouts in North America, UK and Italy. This project aims at investigating major mechanisms of market simulation techniques including impacts from load diversity and approaches to defining appropriate new generation entry into the market. From the outcome of this project the National Electricity Market will be able to manage the uncertainties of load diversity (one of the most common blackout causes), and efficiently minimise risk associated with decisions on new generation entry to enhance electricity supply infrastructure.

It increases our understanding of the impact of climate change policies relating to mandatory targets for greenhouse gas reduction helping to build Australia’s research capacity in the national priority area of an environmentally sustainable Australia. The anticipated methodology can also be seen as protecting the security of power infrastructure as well. Maintaining a critical energy infrastructure protects our way of life and ensures ongoing social, economic and environmental well being of Australia.Read moreRead less
A methodology for the control of harmonics due to large distorting loads. The ideal electricity supply has a voltage of prescribed frequencey and value with a sinusoidal waveshape. Modern electronic equipment such as digital commuication equipment and automatic manufacturing lines draw non-sinusoidal currents which distort the voltage waveform. Electricity suppliers are responsible for limiting voltage distoration to levels set by national standards. Techniques have been developed to allow them ....A methodology for the control of harmonics due to large distorting loads. The ideal electricity supply has a voltage of prescribed frequencey and value with a sinusoidal waveshape. Modern electronic equipment such as digital commuication equipment and automatic manufacturing lines draw non-sinusoidal currents which distort the voltage waveform. Electricity suppliers are responsible for limiting voltage distoration to levels set by national standards. Techniques have been developed to allow them to determine the maximum level of current distortion to which a particular customer is entitled. This project will developand verify a method for determining if a particular customer exceeds that entitlement.Read moreRead less

There is a growing demand for high power and medium voltage energy conversion systems in a wide range of applications, including Rail, Renewable Energy, Defence and Electricity Distribution. Multicell-type multilevel converters are a very attractive means of satisfying this demand, but only if the cell voltages can be precisely regulated so as to ensure protection of the converter while simultaneously ensuring the synthesis of switched waveforms with the required spectral quality. This project offers the potential to eliminate this barrier to the use of Multicell converter technology. In addition this project emphasises the development and training of people skilled in the design and development of this technology.Read moreRead less
Towards a unified theory of constrained control and estimation. The project will investigate the implications of duality and other connections between constrained control and estimation. We believe that the research will result in a richer understanding of these problems. In particular, we envisage an impact in at least four areas: (i) Computational issues, i.e., development of more efficient algorithms for constrained problems. (ii) Geometry of constrained problems, by extending recent results ....Towards a unified theory of constrained control and estimation.

Parsimonious Quantization in Signal Processing and Control. In today's society there is an abundance of data. Indeed, it could be argued that we suffer from data 'overload'. Thus to turn 'data' into actions, the need for parsimony in signal processing and control arises. For that purpose, the data must be sampled (in time) and quantized (in space). Within this context, the current project is aimed at understanding aspects of sampled parsimonious quantization.
