With the development of distributed generation technology

the access to the distributed power（DG）with certain capacity in the distribution grid plays a significant role in improving the power supply quality of the distribution network

reducing grid loss level of system and improving the operation economy.In view of such issue as position of the distribution power in the grid and optimal allocation of capacity in this paper

the multiple-objective optimal configuration model concerning the totalcost of construction and operation of the distributed power and grid loss of the system are set up. A kind of hybrid optimization algorithm based on improved AGSO and BAS is proposed to solve the distributed power optimization model.After getting Pareto solution set by calculation

the final power allocation scheme is selected from the set by theuseoftheinteractivefuzzystrategy.Finally

the IEEE 33 node distribution network system is simulated as anexample

the reasonableness of the model and the effectiveness of the method are verified. The grid loss of the system is optimized by the use of hybrid algorithm and AGSO algorithm respectively. It is shown by the resultcomparisonthattheconvergenceandoptimizationaccuracyof theproposedhybridalgorithmarebetter
