Synchronization Pathways and Resilience in Power Grids
Cook Hyun Kim, Jihye Kim, Sangjoon Park +1
Ensuring a sustainable energy supply requires maintaining power-grid stability. Rotor dynamics are governed by the swing equation, which takes the form of a second-order Kuramoto m…
Paths to synchronization in the Kuramoto model with inertia
Cook Hyun Kim, Yeomoon Kim, Stefano Boccaletti +1
Synchronization is ubiquitous across natural and synthetic systems, yet most prior studies focus on the inertia-free Kuramoto model and do so at the macroscopic level. In this stud…
Cluster-Mediated Synchronization Dynamics in Globally Coupled Oscillators with Inertia
Cook Hyun Kim, Jinha Park, Young Jin Kim +3
Globally coupled oscillator systems with inertia exhibit complex synchronization patterns, among which the emergence of a couple of secondary synchronized clusters (SCs) in additio…
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…
Hybrid Synchronization with Continuous Varying Exponent in Decentralized Power Grid
Jinha Park, B. Kahng
Motivated by the decentralized power grid, we consider a synchronization transition (ST) of the Kuramoto model (KM) with a mixture of first- and second-order type oscillators with…
