基于负荷转移系数的电气介数在电网结构脆弱性评估方法中的应用
Research on structure vulnerability of grid assessment method based on the electrical betweeness of load transfer coefficient
摘要
Abstract
The grid vulnerability , as the extension of safety problem in power system , has great significance to be fur-ther researched .In this paper , according to the calculation method of the electrical betweenness based on load transfer coefficient , considering the influence between the power infused of the generator and load nodes , the structural vulnera-bility assessment model and index are proposed , which reflects the network parameters and operation parameters in the current operating mode .Taking the actual output power as the weight of the load transfer coefficient , the assessment model, which considers the effect of reactive powers makes assessment results more accurate .Finally, a chain of random attack and intentional attack are used to text on the IEEE 39 node system , the paper verifies the effectiveness and supe-riority of the assessment model by the analyzing the changes of the biggest connected region after being attacked .关键词
