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.
