Abstract:In the past decade, the electric power industries world-wide have
experienced a significant period of change and reform. Traditional
vertically-integrated power systems have been progressively
deregulated into competitive electricity markets with profound
changes on both system operation and management. In many cases, this
reform has been, however, mainly directed by economists, lawyers,
regulators and politicians above power engineers. Consequently, many
technical issues, such as system security and ancillary services
management in the electricity markets, haven't been attended to
appropriately as evidenced in a series of recent catastrophic
blackouts throughout the world.
To address the system security in the deregulated power systems, a
new market management framework has to be designed properly, which
is the main focus in the first stage of this research. The proposed
framework features an Ancillary Services market integrated with the
electricity spot market. The structure and the dispatching algorithm
of the integrated market have been designed and developed
respectively. In addition, market forecasting models for both
electricity loads and prices have also been developed as an
essential part of the proposed framework. Various new techniques,
such as Genetic Algorithms, Neural Networks and Wavelet Analysis,
have been applied in the development to achieve optimal market
dispatching and enhanced forecasting results.
With the initial framework obtained, the second stage of the
research will continue to analyse the market management and planning
issues aiming at achieving a comprehensive electricity market
framework. Since the Independent System Operator (ISO) plays a key
role in market management and operations, such as the dispatching
and various planning activities, the analysis of the ISO's decision
making processes involved in those operations will be the main focus
in this stage. A number of advanced decision making theories, such
as the Rank Dependent Expected Utility (RDEU) theory, will be
investigated to select the best suitable ones for the power market
application. Security analysis in electricity markets and system
expansion planning will also be relevant research topics in this
stage.
The research aims at achieving the co-optimisation of system
security and market benefits. The final product will be a
comprehensive electricity market, particularly the Ancillary
Services market simulation, management and operations framework,
which can be served in most pool-type electricity markets practised
in California, USA, UK, Australia and other countries. The thesis is
expected to complete by June 2005.
Biography:Zhao Xu received his B.Eng from Zhejiang University, China in
1996. After graduation, he has worked in Huaneng Power International
and ABB (Beijing) respectively. From 1999, he was with the National
University of Singapore for his M.Eng study. He is currently
pursuing the PhD at the University of Queensland, Australia. His
research interests include electricity market planning and
management, power system stability and security, and AI applications
and signal processing in power systems, power electronics modeling
and simulation.
