In this paper, we propose to study on sufficient control of complex networks which is to control a sufficiently large portion of the network, where only the quantity of controllabl…
Self-Triggered Scheduling for Boolean Control Networks
Min Meng, Gaoxi Xiao, Daizhan Cheng
It has been shown that self-triggered control has the ability to reduce computational loads and deal with the cases with constrained resources by properly setting up the rules for…
Effects of Initial State on Opinion Formation in Complex Social Networks with Noises
Yi Yu, Vu X. Nguyen, Gaoxi Xiao
Opinion formation in complex social networks may exhibit complex system dynamics even when based on some simplest system evolution models. An interesting and important issue is the…
Crash dynamics of interdependent networks
Jie Li, Chengyi Xia, Gaoxi Xiao +1
The emergence and evolution of real-world systems have been extensively studied in the last few years. However, equally important phenomena are related to the dynamics of systems'…
Towards a Universal Approach for Identifying Cascading Failures of Power Grids

This paper addresses the sweep coverage problem of multi-agent systems in uncertain regions. A new formulation of distributed sweep coverage is proposed to cooperatively complete t…
A Model Predictive Approach to Preventing Cascading Failures of Power Systems
Chao Zhai, Hehong Zhang, Gaoxi Xiao +1
Power system blackouts are usually triggered by the initial contingency and then deteriorate as the branch outage spreads quickly. Thus, it is crucial to eliminate the propagation…
Comparing Different Models for Investigating Cascading Failures in Power Systems
Chao Zhai, Hehong Zhang, Gaoxi Xiao +1
This paper centers on the comparison of three different models that describe cascading failures of power systems. Specifically, these models are different in characterizing the phy…
Identifying Critical Risks of Cascading Failures in Power Systems
Hehong Zhang, Chao Zhai, Gaoxi Xiao +1
Potential critical risks of cascading failures in power systems can be identified by exposing those critical electrical elements on which certain initial disturbances may cause max…
Modeling and Identification of Worst-Case Cascading Failures in Power Systems
Chao Zhai, Hehong Zhang, Gaoxi Xiao +1
Cascading failures in power systems normally occur as a result of initial disturbance or faults on electrical elements, closely followed by errors of human operators. It remains a…
