一种通过贡献矩阵评估电力系统脆弱性的方法
System Vulnerability Assessment Based on Contribution Matrix
摘要
Abstract
With the rapid development of network technology, safe and stable operation of power system has attract-ed more and more attention. This paper puts forward a method of vulnerability assessment of power system based on contribution matrix. The basic idea is derived from the generation of its assessment evidence along with corre-sponding index raw data source in the risk assessment. Then, according to selected model structure matrix the con-tribution of evaluation evidence is established. Finally, combining D-S evidence theory and the basic probability, the paper distributes the mass matrix, selecting index of single point trust value as the whole vulnerability risk as-sessment results. Through the concrete example, it verifies the feasibility. The method can combine the correlation of the indexes, which is more effective for comprehensive evaluation system of vulnerability risk.关键词
