Abstract

In order to meet actual situations for fault recovery of distribution network with micro grid, a strategy that micro grid runs firstly with important loads in islanding mode is studied. Generating islanding, the dynamic changes of the various DGs and loads in non-fault zone should be considered, and the dynamic importance degree of each load will be calculated as the inspired conditions for the subsequent islanding search. Whether the load adds to islanding depends on the dynamic importance degree of the load in this paper. The reliability of islanding operation will be analyzed in islanding search. The proposed strategy can control the direction of islanding search and give priority to the recovery of important loads. Also, the balance between the stable islanding and the maximum use of renewable energies can be ensured. The effectiveness of the proposed strategy will be verified by the improved 33-bus system.
