Cascade Failures — Power Grid Network

A single node failure redistributes load via DC power flow. Overloaded nodes fail in sequence, causing cascade blackouts. Click a node to trigger failure.

Node fails when load > α × initial load
DC Power Flow:
Pᵢⱼ ∝ (θᵢ − θⱼ)/Xᵢⱼ
Cascades: failure → redistribution → new overloads.
