A Two-Stage Resilience Enhancement for Distribution Systems Under Hurricane Attacks

Hurricane events can cause severe consequences to the secure supply of electricity systems. This article designs a novel two-stage approach minimize hurricane impact on distribution networks by automatic system operation. A dynamic model is developed, which has variational wind intensity and moving path. The then presents resilience enhancement scheme that considers predisaster strengthening postcatastrophe reconfiguration. pre-disaster stage evaluates load importance an improved PageRank algorithm help deploy precisely. Then, combined soft open point networked microgrid strategy applied enhance resilience. Load curtailment quantified considering both power unbalancing line overloading. To promote computational efficiency, particle swarm optimization solve designed model. 33-bus employed demonstrate effectiveness proposed method. results clearly illustrate hurricanes curtailment, be significantly reduced appropriate network reconfiguration strategies. provides operators powerful tool systems against extreme events, reducing curtailment.
