Power System Security in a Deregulated Market

Speaker: Dr Zhao Dong, ITEE

When: 03.00PM, Wednesday 22 Oct 2003

Venue: 78-420

Host: A/Prof Janet Wiles

Abstract:

  Power industry has been experiencing dramatic changes from a
  vertically integrated industry into a deregulated competitive
  electricity market over the past decade. The ability of the power
  system to supply electricity securely is essential to the operation
  of the electricity market. The electricity market has to follow the
  physical power system constraints as well as the market rules aimed
  at maximum profit for suppliers, lower prices for consumers and an
  overall maximum social welfare.

  Following recent advances in deregulation, the power systems have
  been increasingly stressed close to the security limit. The market
  structure also requires more comprehensive and effective means to
  encourage new entries to the electricity market in generation as
  well as transmission services. The economical and social impact of
  recent black out in Northeast America, UK and Italy has again risen
  the concern about power system security in the deregulated
  electricity market.

  This seminar presents the techniques for power system security
  assessment, both deterministic and probabilistic to cover the
  characteristics and uncertainties in the power system. Market
  mechanisms are also presented aiming to achieve an effective and
  competitive market which also enhances the system security as a
  co-optimisation problem. Techniques such as market demand and price
  forecast, transmission pricing, ancillary services, numerical
  methods and advanced optimisation techniques using evolutionary
  computation approaches are important for this research area of power
  system security in a deregulated market.

Biography:

 
  Dr ZhaoYang Dong is awarded PhD in Electrical Engineering from the
  University of Sydney in 1999. He is now lecturer at the School of
  Information Technology and Electrical Engineering. Dr Dong's
  research interests are mainly in power systems engineering,
  electricity market and computational intelligence. He has published
  over 50 technical papers and book chapters. Dr Dong is active in
  power systems engineering research, with various industrial
  supported research projects including a (power system) probabilistic
  small signal stability assessment project from electric power
  research institute (EPRI), USA.
