The optimal planning of Distributed Generation （DG） is researched. Under the condition that the single capacity, number and position of Distributed Generation are uncertain, an optimal objective function of active power loss for distribution network with DG is established, and the voltage level constraint is introduced which is merged into objective fimction in the form of punishment factor. The Particle Swarm Optimization （PSO） algorithm and the calculation program of power flow are programmed based on Matlab software. An improved PSO algorithm is used to optimize the planning of DG and the optimal scheme is attained at last. Through the case analysis, the method is proved to be correct and effective.
