Modified Genetic Algorithm in Power System Application

Reactive power optimization is an effective method for improving the electricity quality and reducing the power loss in power system. Reactive power optimization is a higher dimensional, nonlinear and complicated optimizing problem, in which continuous and discrete variables coexist. This article presents "cataclysmic GA", combining the “Roulette Wheel” and “Tournament”. Self-adaptive adjusting operators in GA based on the number of iterate and performance of units, speeds up the con-vengeance. The IEEE6 power system, are taken in optimization.
