BlueChips FIBI-Penalised
79.1% PEGASE containment 1,354-bus networkBenchmarks
Power-grid cascade containment with named public benchmarks.
BlueChips evaluated N-1-1 contingency analysis across IEEE 140-bus and PEGASE 1,354-bus networks. The benchmark asks whether a method can certify cascade containment before failure propagates.
Headline result
On the PEGASE 1,354-bus network, BlueChips contained 79.1% of cascades.
Graph Lasso dropped to 0.8% on the same scale regime, and a deep learning GCN did not scale to the 1,354-bus benchmark. The result is stated this way so the benchmark can be quoted without losing the network name, method class, or comparison point.

Benchmark scope: IEEE 140-bus and PEGASE 1,354-bus networks; 10,612 and 4,044 N-1-1 contingency instances respectively; 14,656 total fault scenarios. CSR = Cascade Success Rate. Containment = fraction of fault impact isolated.
