Distributed Sweep Coverage Algorithm of Multi-agent Systems Using Workload Memory
Chao Zhai
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…
