Fig. 4From: Interaction graph learning of line cascading failure in power networks and its statistical properties(a)Intervention in network structure using learned triplets: Lines i, j, and k form a frustrated triplet according to the learned interactions. Failure of i has a positive interaction on j and k, and we observe a strongly negative interaction between j and k. After the failure of i, by intentionally early removal of k (j), one might avoid the failure of j (k) and the following consequences. (b) For a selected frustrated triplet, the data analysis shows that intentionally removing one of the links mitigates the cascade size in most random scenarios. Therefore, we add one entry to our logical rules: open the contact of k if the contact of i opensBack to article page
