考虑不确定性故障的节点综合脆弱性评估
Comprehensive vulnerability assessment of nodes considering uncertain faults
摘要
Abstract
The vulnerability assessment of power system can select a potential weak link in the system,which is the basic work to prevent and reduce power system blackout.With the comprehensive consideration of energy margin and sensitivity,the vulnerability index of node is proposed,and vulnerability risk factor is considered to characterize the capability of nodes,and the network topology parameters of nodes are considered.Considering the running state,the fault factors and the structural properties of the nodes,the comprehensive vulnerability assessment model is established.The model overcomes the shortcomings that the traditional vulnerability assessment method doesn't consider the uncertain fault factors.The simulation analysis of IEEE-30 bus system verifies the rationality of the proposed method.关键词
