EMERGENCY CONTROL FOR POWER SYSTEM SEPARATION. In 2003 we saw major blackouts of power systems for US/Canada, Italy and London leading to billions of dollars of lost production and major impacts on many peoples lives. One aspect contributing to some of these is the control of system dynamic response and the targeted use of emergency controls such as load and generator shedding. This project is contributing to the development of an integrated control response such that appropriate levels of emerg ....EMERGENCY CONTROL FOR POWER SYSTEM SEPARATION.

Advanced Planning Tools for the Prevention of System-wide Blackouts of Large Power Systems. In 2003 there had been major power blackouts in US/Canada, Italy and in Scandinavia leading to billions of dollars of lost production and had raised concern about national security. Prevention of blackout should be one of the highest priorities of the electricity industry. National security for any critical infrastructure of any country is more vulnerable for a prolonged blackout.

In 2003 there had been major power blackouts in US/Canada, Italy and in Scandinavia leading to billions of dollars of lost production and had raised concern about national security. Prevention of blackout should be one of the highest priorities of the electricity industry. National security for any critical infrastructure of any country is more vulnerable for a prolonged blackout. This project will provide comprehensive planning tools to prevent blackouts in the Australian National Electricity grid. Any benefit to electricity industry will finally result in further benefits to the national economy and security as a whole.

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

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
