Fault location of DG distribution network based on improved NGO algorithm

In order to solve the problems of difficult fault location and low positioning accuracy of DG distribution network, a fault location model of DG distribution network based on improved NGO algorithm was proposed. Firstly, a suitable fault location model was established. Secondly, chaos mapping is used to improve the population quality of NGO algorithms, and adaptive weights are introduced to improve the global development ability of the algorithms. Finally, through simulation analysis, the experimental results show that the localization model is practical and feasible, and the INGO algorithm can solve the problem of fault location well.
