Towards a Universal Approach for Identifying Cascading Failures of Power Grids
Chao Zhai, Gaoxi Xiao, Hehong Zhang +1
Due to the evolving nature of power systems and the complicated coupling relationship of power devices, it has been a great challenge to identify the contingencies that could trigg…
Identification and Analysis of Cascading Failures in Power Grids with Protective Actions
Chao Zhai, Gaoxi Xiao, Hehong Zhang
This paper aims to identify and analyze the initial contingencies or disturbances that could lead to the worst-case cascading failures of power grids. An optimal control approach i…
Contingency Identification of Cascading Failures in Power Transmission Networks
Chao Zhai, Hehong Zhang, Gaoxi Xiao +1
Due to the evolving nature of power systems and the complicated coupling relationship of power devices, it has been a great challenge to identify the contingencies that could trigg…
Risk Identification of Power Transmission System with Renewable Energy
Chao Zhai, Gaoxi Xiao, Hehong Zhang +1
This paper aims to investigate the risk identification problem of power transmission system that is integrated with renewable energy sources. In practice, the fluctuation of power…
Cooperative Control of TCSC to Relieve the Stress of Cyber-physical Power System
Chao Zhai, Gaoxi Xiao, Hehong Zhang +1
This paper addresses the cooperative control problem of Thyristor-Controlled Series Compensation (TCSC) to eliminate the stress of cyber-physical power system. The cyber-physical p…
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…
