One of the most common and efficiency in distribution network for power factor improvement and voltage regulation control is shunt capacitor bank. The most important parameter in power factor improvement and voltage regulation process is the location and value of the capacitor bank. Many issues should be considering in Capacitor bank location select. In this paper use simulation of IEEE 14 bus on Matlab Simulink an use genetic algorithm to select capacitor bank location and values base on fitness function included Cost and P.F values. Result shows construability of genetic algorithm in cost and PF values depend on client demand by Capacitor bank location optimization location and value.
