The distribution network planning plays an important role in ensuring the whole system operation and lays the foundation of the power quality.With the development of society,the environmental pollution is more and more serious and the land available is becoming more and more tense,which is limited by land resources.As a result,the researchers are gradually turning to the distribution network of environmental friendly and small area distributed power.In the research of distribution network with distributed power supply,this paper discusses three aspects.Firstly,the technology of distributed power generation technology is introduced in this paper,including wind power,biomass power generation,photovoltaic power generation and fuel cell generation,and the influence caused by distributed power compared with the traditional power generation technology is anlyzed.Secondly,the mathematical model of multi-objective optimization problem is established and calculated in this paper,and the optimization selection of the global optimal particle and calculation of diversity loss problem are studied considering adaptive grid method and fuzzy method of global best position.Finally,the defects of distribution network with distributed power in hand are analyzed,and the maximum static voltage stability margin of the DG multi-objective programming model is established considering environmental benefits,the network loss reduction and the maximizing static voltage stability margin,while the problem of location and capacity of distributed power supply is analyzed.
