Abstract

Based on the improved electrical betweenness and voltage stability theory, considering the importance of the structure of the grid and the current operational state of the power system, a comprehensive vulnerability assessment model and index based on the method of AHP-grey relation degree is introduced.Aiming at the shortcomings of only considering one of the structural vulnerability and state vulnerability assessment model, integrated expert's subjective opinion and objective data information, the comprehensive vulnerability assessment model can generally describe the vulnerable characteristics of assessment system, and scientifically identify weak nodes in the system.Finally based on the simulation of IEEE39 node system, it is verified the rationality and validity of the assessment index.
