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.

POWER DELIVERY IN A DEREGULATED ENVIRONMENT. The recent deregulation of the power industry has opened up new technical challenges that must be addressed in order to ensure fair and equitable market operation. Significant among these is the availability of alternative routes for the delivery of power, between and across different ownerships. In this scenario, a major challenge is to determine the minimum cost contractual arrangement for the delivery of required power. To achieve this, new techniq ....POWER DELIVERY IN A DEREGULATED ENVIRONMENT. The recent deregulation of the power industry has opened up new technical challenges that must be addressed in order to ensure fair and equitable market operation. Significant among these is the availability of alternative routes for the delivery of power, between and across different ownerships. In this scenario, a major challenge is to determine the minimum cost contractual arrangement for the delivery of required power. To achieve this, new techniques for the analysis of power systems are required. This proposal aims to provide solutions to these analysis problems and hence to provide software to assist with market operation.Read moreRead less
Stability Analysis and Control for Large Scale Power Systems Incorporating FACTS Devices. Power system stability analysis and control is one of the most important issues in power systems. The problem becomes more serious in power systems with long transmission lines, such as the transmission systems in Australia. The ability of a power system to maintain stability depends to a large extent on the controls available on the system. Consequently, the study and design of power system controls are ve ....Stability Analysis and Control for Large Scale Power Systems Incorporating FACTS Devices. Power system stability analysis and control is one of the most important issues in power systems. The problem becomes more serious in power systems with long transmission lines, such as the transmission systems in Australia. The ability of a power system to maintain stability depends to a large extent on the controls available on the system. Consequently, the study and design of power system controls are very important for expanding systems. This project aims at investigating into stability assessment and control of large scale interconnected power systems incorporating FACTS (Flexible AC Transmission System) devices in a deregulated electricity market.Read moreRead less
Investigation of key factors affecting the polarisation based diagnostics of power transformers. To avoid system wide power interruptions, major assets in the electricity network must be always operating satisfactorily. One of the key assets in the electricity network is the power transformer. Currently many transformers are over 50 years old and failure of a transformer may result in long interruptions in supply and the loss of millions of dollars in revenue. The ageing of transformers needs to ....Investigation of key factors affecting the polarisation based diagnostics of power transformers. To avoid system wide power interruptions, major assets in the electricity network must be always operating satisfactorily. One of the key assets in the electricity network is the power transformer. Currently many transformers are over 50 years old and failure of a transformer may result in long interruptions in supply and the loss of millions of dollars in revenue. The ageing of transformers needs to be properly monitored to avoid catastrophic failures. This project will provide an innovative solution for the better understanding of the ageing processes of transformers and help
managers make correct decisions for maintenance and replacement strategies.

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

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

The aim of the program is to demonstrate the superconducting magnesium diboride (MgB2) wires with improved upper critical field (Hc2,) appropriate for large-scale applications. The basic idea will be based on the two-gap superconductivity to add well-distributed impurities which will act as scatterers, increasing resistivity, and thus Hc2. The core innovation of this proposal is based on the recent breakthrough in MgB2 that was made by the CIs through nano-SiC particle doping, which achieved a record high Hc2 in bulk form and enhancement of critical current density, Jc, in magnetic fields by an order of magnitude. The expected outcome is the development of superconducting MgB2 wires and coils with high Hc2 and Jc for MRI applications.Read moreRead less
