Research On The Optimal Configuration Of Distributed Generation In Distribution Network

With the continuous growth of power load,the disadvantages of the traditional centralized single power supply system gradually appear.It is the development trend of the future power grid to combine the traditional power grid with the distributed generation and give full play to the advantages of the distributed power generation.This paper firstly introduces the working principle of the common structure of the distributed power supply and grid method Secondly analyzes the distributed power grid network loss of power distribution network voltage power quality reliability of relay protection and the effects of power distribution network planning Then chain distribution system for example,with 18 nodes of the distributed power grid capacity and location of the distribution network voltage and the impact of network loss are analyzed in the simulation.Finally established in power distribution network loss minimum and node voltage offsets the smallest multi-objective optimal allocation of distributed power model in the process of model,both the unified dimension weighted after the multi-objective function optimization into single objective function optimization problem,but with the constraints in the form of punishment factor will be incorporated into the objective function Then on IEEE33 distribution test system for example,using the algorithm of dragonflies respectively by the distributed power system network loss is minimal Minimum node voltage deviation and both after unified dimension weighted minimum value of multi-objective function for the optimization allocation model are applied to solve the three optimization configuration scheme and the optimized results were analyzed At the same time,the dragonfly algorithm and genetic algorithm and particle swarm algorithm are compared,the result of the optimal allocation model for verified the feasibility of the algorithm is adopted.
