Abstract:Many conventional gradient-based algorithms have been used to solve
the power system optimization problems. However, their common
disadvantages are a) requiring continuous and differentiable
objective functions, b) easy to be trapped into local minimum, and
c) difficult to handle discrete control variables. To overcome these
disadvantages, more flexible evolutionary algorithms including
genetic algorithm, evolutionary strategy, evolutionary programming
and particle swarm optimization have been studied since
mid-1990s. Some works have recently been performed in the
Computational Intelligence Applications Research Laboratory
(CIARLab) in the Department of Electrical Engineering at HKPolyU on
the applications of evolutionary algorithms in power system
optimization problems.
In this seminar, a comprehensive study on some recently developed
evolutionary programming techniques for the ORPF flow problem
carried out at CIARLab will first be presented. It then describes
how by comparing the performances of four control schemes of the
strategy parameter (CSSPs) of evolutionary programming, two
principles for designing effective CSSPs can be identified and used
to develop two improved CSSPs. Performance studies of the improved
evolutionary programming methods conducted on the IEEE 14-, 30- and
118-bus test systems will also be described.
