In order to control the harmonics caused by non linear loads in distribution system effectively, three methods, i.e., system pole and its sensitivity analysis method, Simulated Annealing and Genetic Algorithm (GA) are presented and compared in this paper. The Genetic Algorithm is mainly analyzed on the basis of practical facts, and some improvement of adaptive GA is carried out. The purpose of the improvement is to overcome the blindness in traditional harmonic analysis methods, reasonably utilize the configuration of filters in distribution network, and obtain the optimal restraint of harmonics in distribution network with less investment.
