Power system composite load modeling. Load modelling remains an open problem (and probably the most important unsolved problem) for the power industry world wide and is a priority for the research community in Australia. Without reliable load models it is impossible to perform accurate power system security assessment, which may lead to power system blackouts causing billions of dollars and hinder national security. This project aims at developing a composite load model and tackles all the up-to ....Power system composite load modeling.

Low-order dynamical models for non-linear fluid behaviour in quasi two-dimensional plasmas. Two complex systems in which a magnetic field imposes two-dimensional fluid motions are turbulent fusion plasmas and magnetospheric plasmas. A distinctive property of 2D flows is the inverse energy cascade, whereby energy streaming into large-scale vortices, coherent structures, or sheared flows gives a remarkable propensity for self-organizing behaviour. This can be exploited to govern or guide our respo ....Low-order dynamical models for non-linear fluid behaviour in quasi two-dimensional plasmas. Two complex systems in which a magnetic field imposes two-dimensional fluid motions are turbulent fusion plasmas and magnetospheric plasmas. A distinctive property of 2D flows is the inverse energy cascade, whereby energy streaming into large-scale vortices, coherent structures, or sheared flows gives a remarkable propensity for self-organizing behaviour. This can be exploited to govern or guide our response to such systems. We propose to investigate the dynamics of momentum and energy exchange in these plasmas, using reduced dynamical models and bifurcation and stability mathematics. Expected outcomes are improved prediction of magnetospheric substorms and confinement of fusion plasmas.

A well known example is the giant magnetoresistance, a phenomena discovered over fifteen years ago that now plays a key role in current high density magnetic disc drives. Future developments will involve spin dependent transport through structures wherein quantum interference effects will be important. Two basic problems facing the construction of a complete theory of transport in such ?mesoscopic? conductors will be solved in this project. The results will provide important insights into the dynamics of spin transport through structures such as magnetic nano-wires.Read moreRead less
