Distributed generation supply connected to a distribution network,it will affect the voltage,line power loss,relay protection,and line flow of the distribution network.Distributed generation supply reasonable configuration is beneficial to the voltage,line power loss,relay protection and economical operation of the distribution network,Considering distributed generation,load characteristics and dynamic reconfiguration of the distribution can reasonable distributed generation sizing and allocationThis paper first briefly introduces three types of distributed generation and gives the mathematical models of Photovoltaic power,wind power,and lead-acid batteries,analyzes the impact of distributed generation access to the distribution network on line power loss,voltage,and relay protection.Second,And Based on the node correlation matrix,a hierarchical forward push back generation power flow calculation capable of adapting to the distribution network reconstruction is established.The equivalent nodes of distributed generation and calculation methods in the power flow calculation process are also introduced.And verify the correctness of the Power flow calculationSecondly,this paper briefly introduces the spider swarm algorithm,analyzes the shortcomings of the vibration formula in the algorithm in engineering applications,and proposes a method based on normalized thinking to process the vibration information based on the shortcomings.At the same time,in order to make the mating link in the algorithm It can be carried out reasonably and efficiently.A new mating behavior condition is introduced,and a mutation link is introduced.At the same time,the algorithm optimization process is given.Finally,the simulation is performed on the particle swarm algorithm and the unmodified spider swarm algorithm.The results are compared to verify the rationality and effectiveness of the improved algorithm.Finally,multiple objective functions are established for the distributed generation size and allocation and converted into a single objective function by the 1-9 scale method.The characteristics of different types of loads are briefly analyzed,the clustering algorithm(Iterative Self Organizing Data Analysis Techniques Algorithm,ISODATA)classifies the load data and wind,light,temperature,and verifies its rationality through simulation.At the same time,it is proposed to ensure that the reconstruction of the distribution network can be effectively performed.A tabu search algorithm with multiple tabu tables is simulated and simulated through a 33-node power distribution network(IEEE33).and other methods are compared to prove the correctness of the algorithm.Finally,The overall process of power capacity fixed capacity location and simulation based on different reconstruction schemes shows that both the reconfiguration time and the number of reconfigurations will have a greater impact on the capacity fixed capacity location of distributed power sources.When the number of constructions is large,the resulting distributed capacity fixed capacity addressing scheme can effectively reduce line losses and improve node voltage.Figure 18 table 10 reference 59...
