Application of bacterial foraging algorithm for fault location in distribution networks with DG

For the difficulty of traditional fault location method brought by DG, an improved bacterial foraging algorithm is applied to fault location in distribution networks with DG. This method abandoned the construction of complex switching functions in the original intelligent bionic method. The relationship between the switch and the line is hided in the network relationship matrix, and the impact brought by DG is hided in the DG matrix. The mathematical model is improved so that it can be better adapt to multi-DG, multi-fault case. Even when the information is distorted, this method still has the ability of fault tolerance. Simulation examples demonstrate the feasibility of this program.
