Dynamic Island Partition Strategy for Active Distribution System with Controllable Load Participation

Island operation is an effective way to maintain the power supply to loads when a failure occurs in the distribution network containing distributed generations (DGs). In this paper, a multi-period dynamic island partition strategy is proposed in order to form more flexible islands for better load recovery. Firstly, based on the Dijkstra algorithm, an initial island partition scheme is acquired, which gives full play to the power supply potential of DGs. Then, with controllable loads participating in dispatch, a multi-objective optimization adjustment model is established to form final dynamic islands. Finally, the results of the case study verify the validity of the proposed method.
