Fault recovery strategy of active distribution network based on source-network-charge-storage coordination optimization

In this paper, a unified model of island division and network reconstruction of active distribution network including distributed power supply and energy storage is constructed, and the fault maintenance strategy and load demand response strategy are considered to realize the integrated operation of "source-network-load-storage". Then the second order cone relaxation technique is used for convex relaxation, and the original model is transformed into a standard mixed integer second order cone model, so as to reduce the complexity of the solution. Finally, IEEE 33 node active distribution network is used to verify the superiority of the proposed fault recovery strategy.
