Abstract: Aiming at the problem of recovery control of active distribution network with microgrid containing distributed generation（DG） after fault, this paper proposes a two-layer power supply recovery strategy for precise load of distribution network considering microgrid voltage support. Firstly, in order to fully quantify the risk of island operation after reconfiguration during the fault period, the risk index of island operation after reconfiguration is defined from the perspective of voltage stability and power balance, and the reconfiguration model is established by using the distributed generation resources of microgrid in the fault period to the greatest extent.Then, aiming at the problem of high difficulty in solving the power supply recovery reconstruction model, the grey wolf optimization algorithm（GWO） and the second-order cone relaxation technique are used to solve the two-layer reconstruction model respectively.Among them, in order to solve the problem that the GWO algorithm guides the population evolution with high-quality solutions, which leads to the limitation of efficiency, the PSO algorithm is used to improve the individual position update process of the GWO algorithm, and the historical information of each gray wolf individual is integrated to construct a more efficient population evolution method.Finally, using the modified IEEE 33 node system, the power supply recovery scheme can be provided under two different types of faults, which verifies the feasibility of the proposed method.
