摘      要：Estimating the potential load curtailments as a result of hurricane is of great significance in improving the paper proposes a three-step sequential method in identifying such load curtailments prior to *** the first step,a twin support vector machine(TWSVM)model is trained on path/intensity information of previous hurricanes to enable a deterministic outage state assessment of the grid components in response to upcoming *** TWSVM model is specifically used as it is suitable for handling imbalanced *** the second step,a posterior probability sigmoid model is trained on the obtained results to convert the deterministic results into probabilistic outage *** outage states enable the formation of probability-weighted contingency ***,the obtained component outages are integrated into a load curtailment estimation model to determine the expected results,tested on the standard IEEE 118-bus system and based on synthetic datasets,illustrate the high accuracy emergency response and the recovery of power *** potential load curtailments in power *** simulation of the proposed method.
