Low-voltage distribution network has the characteristics of large number of nodes and branches, radial network and three-phase asymmetry in normal operation, which directly affects the power quality of users. In this paper, the load variation, the three-phase asymmetry and the capacity attenuation of capacitors are considered, and the state evaluation and three-phase capacity planning of LV reactive power compensator are studied. Genetic algorithm is used to realize economical and efficient control effect of bus voltage stability through reasonable planning of finite compensation equipment in multi-node system. Experimental results show that the proposed method can effectively optimize the location and capacity of the compensation device, and can improve the overall voltage level of distribution network economically and reasonably.
