A Shy Voter Model: Entropy Flux in Opinion Formation
Cook Hyun Kim, Sangjoon Park, B. Kahng
Some voters conceal their opinions, causing a mismatch between visible and private opinions in polls. Conventional voter models do not account for such concealment. Here, we introd…
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…
AI-Driven Stabilization in Power Grids through Controlling Line Admittances
Sangjoon Park, Hoyun Choi, Yongsun Lee +3
The global transition from traditional power plants to renewable energy sources introduces new challenges in grid stability, primarily because inverter-based technologies provide i…
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…
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…
