According to the feature of variable structure of distribution network and flexible control property of load, a structure optimization strategy for faulted distribution network containing distribution generations is proposed and divided into two subproblems, namely island partitioning and reconfiguration of residual network. The subproblem of island partitioning is turned into satisfiability problem, in the first stage the implicit enumeration is utilized to obtain the initial partitioning scheme, and in the second stage by means of checking static survivability constraint and combining with power flow calculation, in which the network loss is taken into account, the interrupted amount of local interruptible load is modified and the amount of reactive power compensation is determined, thus the final island partitioning scheme is attained. The optimal switcher combination in the subproblem of reconfiguration of residual network is solved by ant colony algorithm. The effectiveness of the proposed strategy is verified by calculation results of a certain actual distribution network with 70 buses.
