| Distribution network is an indispensable part of the power system,is the bridge of power transmission and consumption,and has a very important impact on our daily life and work.Distribution network reconfiguration is one of the key technologies for the optimal operation of power system network,and it is also an important content for automatic search of distribution network system.In the normal operation mode,the test director can infer the effective data results according to the load contained in the power system,and then reconstruct the effective data information of the distribution network.Generally,distributed power refers to the micro power generation facilities directly distributed around the distribution network or load of several kilowatts to 50 MW.With the continuous development of contemporary society,energy shortage and environmental pollution have become serious problems facing the world.Distributed power generation(DG)is widely concerned because of its flexibility,reliability,economy and other characteristics.However,the grid connected operation of a large number of distributed generation will change the network structure,resulting in the change of power flow distribution,which will seriously affect the power loss,power quality and other aspects of the distribution network.Therefore,it is of great importance and practical value to study the reconfiguration of distribution network with distributed generation.In this paper,the reconfiguration of distribution network with distributed generation is studied as follows:(1)we introduce some of the widely distributed energy,analyze the impact on the quality of the power,and divide into four categories.PQ,PV,PI,PQ(V)is a better text,along with mathematical models,through the access method.(2)we propose two conventional discovery algorithms,namely particle swarm algorithm and firefly algorithm.These are integrated into the mixed smart algorithm IFA-PSO.We have established a redesigned sales network model with minimum effective loss and load balance inde.The forward and backward method is used to calculate the power flow of the distribution network with distributed power supply,and the feasibility and advantages of the algorithm are verified by taking the standard ieee33 bus system as an example. |
