Research on the Reconfiguration of Multi-Objective Distribution Network Based on Improved Newton Method

A reasonable distribution network structure can deliver the electrical energy to the terminal with the minimum loss. Distribution network reconfiguration, is to reconstruct the distribution network. According to the different requirements, reconfiguration adjust the branch switch state of the network. This paper first introduces the related concepts and research status of distribution network reconfiguration, and establishes a mathematical model with the objective function of minimizing network loss and system voltage deviation. Secondly, the application of Newton's method in distribution network is described. Then, the basic principle of binary particle swarm optimization (BPSO) is deeply studied, and it is successfully applied to distribution network reconfiguration, and the program is written with VS2017. Through the reconstruction of IEEE 33 node example, the effectiveness and practicability of the reconstruction algorithm are verified.
