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…
Effective vaccination strategy using graph neural network ansatz
Bukyoung Jhun
The effectiveness of vaccination highly depends on the choice of individuals to vaccinate, even if the same number of individuals are vaccinated. Vaccinating individuals with high…
Resolving mean-field solutions of dissipative phase transitions using permutational symmetry
Minjae Jo, Bukyoung Jhun, B. Kahng
Phase transitions in dissipative quantum systems have been investigated using various analytical approaches, particularly in the mean-field (MF) limit. However, analytical results…
Effective epidemic containment strategy in hypergraphs
Bukyoung Jhun
Recently, hypergraphs have attracted considerable interest from the research community as a generalization of networks capable of encoding higher-order interactions, which commonly…
Abrupt transition of the efficient vaccination strategy in a population with heterogeneous fatality rates
Bukyoung Jhun, Hoyun Choi
An insufficient supply of effective SARS-CoV-2 vaccine in most countries demands an effective vaccination strategy to minimize the damage caused by the disease. Currently, many cou…
Topological estimation of the latent geometry of a complex network
Bukyoung Jhun
Most real-world networks are embedded in latent geometries. If a node in a network is found in the vicinity of another node in the latent geometry, the two nodes have a disproporti…
Simplicial SIS model in scale-free uniform hypergraph
Bukyoung Jhun, Minjae Jo, B. Kahng
The hypergraph offers a platform to study structural properties emerging from more complicated and higher-order than pairwise interactions among constituents and dynamical behavior…
Electronic structure of charged bilayer and trilayer phosphorene
Bukyoung Jhun, Cheol-Hwan Park
We have investigated the electronic structure of charged bilayer and trilayer phoshporene using first-principles, density-functional-theory calculations. We find that the effective…
