From Spatial to Spectral: Network Renormalization via Dynamical Correlations
Cook Hyun Kim, B. Kahng
Network renormalization has traditionally relied on spatial adjacency-grouping nearby nodes together, but this approach fails to capture the dynamical correlations that govern syst…

Optimal location of reinforced inertia to stabilize power grids
Sangjoon Park, Cook Hyun Kim, B. Kahng
The increasing adoption of renewable energy sources has significantly reduced the inertia in the modernized power grid, making the system more vulnerable. One way to stabilize the…
