    With the increasing prevalence of distributed generators(DGs), islanded operation based on distributed generation is considered an important means to enhance system reliability and resilience. This paper studies the main factors that should be considered in the islanding division of distribution networks and establishes a mathematical model for islanding partitioning. It proposes a method for determining the maximum power supply range of distributed energy based on the reachability matrix and power circle algorithm, which improves computational efficiency. The islanding partitioning scheme of the distribution network is solved using a dynamic programming method based on breadth-first search. A region correction method is applied to modify the maximum power supply area by considering controllable loads and prioritizing the restoration of critical loads and power flow validation is used to demonstrate the effectiveness of the proposed method. Finally, simulation analysis is conducted to verify the effectiveness of the proposed algorithm.
