In order to solve the problem that the search efficiency and optimal solution quality of intelligent optimization algorithm cannot be taken into account in distribution network reconfiguration, a distribution network reconfiguration method based on improved sparrow search algorithm is proposed. Firstly, the ordered basic loop matrix is formed according to the distribution network topology and branch information, and the dynamic coordination matrix is generated with the help of the heuristic rules in the optimal flow pattern; secondly, aiming at the sparrows with different division of labor in the sparrow search algorithm, the position update rules of the explorer are improved by using the dynamic coordination matrix to prevent it from falling into local optimization. At the same time, a static coordination matrix is constructed to deeply mine the adjacent schemes of the optimal individual. Finally, the simulation results of the IEEE33 node system show that the improved sparrow search algorithm has higher optimization stability and faster convergence speed, and can meet the requirements of optimal solution quality and search efficiency when solving the distribution network reconfiguration problem.
