Fault Location in Distribution Network with Distributed Generations Based on Improved Binary Gravitational Search Algorithm
摘要
Abstract
To improve the accuracy and rapidity of fault location in distribution network with distributed generations (DGs),this paper improves the location updating formula in the traditional binary gravitational search algorithm(BG?SA)and adds a population initialization formula to BGSA,so that the improved algorithm can be applied to the fault lo?cation in distribution network.Considering the problems of premature convergence and optimization accuracy in BGSA, an self-adaptive attenuation coefficient α is defined,which improves the accuracy of BGSA effectively. The improved BGSA is applied to the fault location in distribution network with DGs,and the feasibility and validity of this algorithm is verified by a numerical example.Results indicate that the proposed algorithm can improve the accuracy of fault loca?tion for complicated distribution network with a fast convergent speed and excellent fault-tolerant ability.关键词
