Aiming at the problem of unsatisfactory effect of distribution network planning,a grid planning model of medium and low voltage distribution network based on particle swarm algorithm was proposed.Taking the minimum loss cost in the line as the objective function,the mathematical model of grid planning of medium and low voltage distribution network was constructed,and the particle swarm optimization algorithm was used to optimize the model;prior to optimization,the particle range was set to meet the set conditions,and then the particle population was initialized,so as to improve the optimization effect of the algorithm and realize the design and optimization of grid planning model of medium and low voltage distribution network based on particle swarm optimization algorithm.The experimental results show that the proposed model has the best line connection rate and passing rate,stable power supply reliability and higher load balance.It shows that the model is practical and can provide reference for medium and low voltage distribution network planning in the future.
