Abstract: As a large number of distributed electric power supplies are connected to the distribution network, the traditional fault recovery method is no longer directly used for the distribution network containing DG. This paper analyzed the operation mode of DG and its positive effect on the fault recovery, discussed the research status of fault recovery strategy, mathematical model and optimization of distribution network containing DG, summarized the advantages and disadvantages of applying different strategies to the distribution network fault recovery in DG condition and indicated the problems and directions of further study in future.
Key words: fault recovery; distributed generation; distribution network; optimization method
