Genetic algorithm has been used to solve the problem of capacitor placement
in power distribution, systems. A new composition of the genetic string ha
s been proposed for the coding of the capacitor placement problem. The prop
osed genetic string represents both the optimum location and the size of th
e capacitor. A number of modifications have also been proposed to improve t
he performance of the simple genetic algorithm in solving the capacitor pla
cement problem. Test results have been presented in support of the superior
ity of the proposed modifications.
