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…
Exploring growing complex systems with higher-order interactions
Soo Min Oh, Yongsun Lee, Byungnam Kahng
A complex system with many interacting individuals can be represented by a network consisting of nodes and links representing individuals and pairwise interactions, respectively. H…
Reinforcement Learning Optimizes Power Dispatch in Decentralized Power Grid
Yongsun Lee, Hoyun Choi, Laurent Pagnier +6
Effective frequency control in power grids has become increasingly important with the increasing demand for renewable energy sources. Here, we propose a novel strategy for resolvin…
Prediction and mitigation of nonlocal cascading failures using graph neural networks
Bukyoung Jhun, Hoyun Choi, Yongsun Lee +3
Cascading failures (CFs) in electrical power grids propagate nonlocally; After a local disturbance, the second failure may be distant. To study the avalanche dynamics and mitigatio…
Betweenness centrality of teams in social networks
Jongshin Lee, Yongsun Lee, Soo Min Oh +1
Betweenness centrality (BC) was proposed as an indicator of the extent of an individual's influence in a social network. It is measured by counting how many times a vertex (i.e., a…
Homological percolation transitions in growing simplicial complexes
Yongsun Lee, Jongshin Lee, Soo Min Oh +2
Simplicial complex (SC) representation is an elegant mathematical framework for representing the effect of complexes or groups with higher-order interactions in a variety of comple…
