The Nodes Vulnerability Assessment to Power Grid based on Time Margin

摘要：

On the basis of the existing research of Basic vulnerability, an index of nodes contingency time margin is defined, for the security assessment of the power system. By guidelines for the preparation of a technical work for the IEEE combining the index of nodes contingency time margin with the assessment of the nodes vulnerability, a new index of the nodes vulnerability assessment to power grid based on time margin was proposed, to assess the nodes voltage vulnerability result of expected contingency. Simulation results on IEEE 14 testing system indicate the effectiveness of the proposed vulnerability assessment method, considering more comprehensive the relay protection, by comparing with the index of nodes voltage vulnerability only considering nodes voltage margin.
