Anticipation of Line Tripping Cascade by Grid Curvature and Entropy

This study develops an Effective Resistance Curvature approach to detect those vulnerable areas/corridors where the thermal limits of overhead conductors could be violated as a consequence of active power re-routing consequential to an earlier line tripping. The proposed curvature analysis is also combined with a local/nodal entropy feature, which visually helps to confirm where the line tripping is occurring.
