Abstract
DG islanding operation can efficiently improve the reliability of customers when main power supply network has a fault. This paper installs the weight model of islanding based on the concept of minimum spanning tree. Then the non-fault area is generated by the minimum tree to form a radial distribution network when the fault is isolated. In the mean time, the tree can be separated by dynamic planning according to the goal of the restoring load as much as possible. Finally, it's to use IEEE distribution system with 118 nodes as an example to separate the island. The result shows that the method is reasonable and valid and the reliability is directly related to the output of DG.
