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…
-core decomposition of hypergraphs
Jongshin Lee, Kwang-Il Goh, Deok-Sun Lee +1
In complex networks, many elements interact with each other in different ways. A hypergraph is a network in which group interactions occur among more than two elements. In this stu…
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…
