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.
