In the intelligent distribution network planning,it is very important to select a reasonable location and optimal sizing for the distributed power supply.Based on the study of distributed power supply planning,the objective function is established on the foundation of the short-circuit current indicators and the voltage stability indicators.This paper proposes the cell membrane mechanism to improve the particle swarm algorithm,and then apply the algorithm to the location and sizing of the distributed generator placement,so as to achieve the best voltage profile stability and improve the short circuit level in a distribution system.According to the constraint conditions that the optimal location and the capacity of the distributed power,the proposed algorithm is applied to IEEE-12 system and IEEE-30 system,verifying the feasibility of the algorithm.
