Lucia
The seminar will consist of an hour long presentation beginning shortly
after 5:00pm. At the conclusion of the presentation the speaker will be
available for questions and discussions.
Light refreshments will be provided.
Abstract
Evolutionary computation offers new paradigms such as Genetic Algorithm (GA)
and Evolutionary Programming (EP) for the determination of the global
optimum solutions for optimisation problems. These evolutionary techniques
have recently been applied to complicated optimisation problems in power
engineering. The GA and EP approaches are adaptive and can be regarded as
search techniques based on an analogy with biology in which a population of
chromosomes evolves generation by generation through natural selection. In
their implementations, a population of candidate solutions evolves to an
optimum solution through the operations of genetic operators.
In this seminar, the methodology of GA and recent works by the presenter on
the enhancement of the robustness and computational efficiency of GA will be
presented. The concept of virtual population will be elaborated. Two
solution acceleration methods and the schemes, which utilise the
acceleration methods, will be described. The seminar then shows how the
enhancement techniques can be embedded into a constrained-GA algorithm for
solving the power flow problem and for the determination of the loadability
limits of power systems. Some preliminary results in using GA to determine
the equilibrium of competitive power markets will also be presented.
Speaker:
Kit Po Wong is Professor of Electrical Engineering with the School of
Electrical and Electronic Engineering, The University of Western Australia.
He obtained MSc, PhD and DEng in 1971, 1974 and 2001 respectively from The
University of Manchester Institute of Science and Technology (UMIST), UK. He
has worked in power system stability, protection, planning, electromagnetic
transient evaluations, and applications of artificial intelligence,
computational intelligence and Wavelet transform to power system planning,
operation and power market. In 1981, 1982 and 1987, he was awarded the Sir
John Madsen medals of the Institution of Engineers, Australia, for his
contributions to electrical engineering. In 1999, he has been Honorary Theme
Editor on electrical engineering, appointed by UNESCO, for an encyclopaedia.
In 2000, he was appointed Honorary Professor of Tsinghua University, China.
He was the general chairperson of the IEEE/CSEE PowerCon2000 conference.
Professor Wong is a Fellow of IEEE, Fellow of IEE, Fellow of HKIE and Fellow
of IE Australia. From 1999-2000, Professor Wong was the chairperson of IEEE
Western Australia Section and was the founding chairperson of the IEEE PES
Chapter in Western Australia. He was awarded the 1999 Outstanding Engineer
Award from the Chapter. He was a recipient of an IEEE Third Millennium Award
in 2000.
