Abstract

The vulnerability of power system is always one of hot areas, which was concerned by many researchers in last several decades. In this paper, a state vulnerability assessment model and index based on the margin of voltage stability is introduced, namely comparing the margin of the actual operating voltage and the critical voltage to assess the state vulnerability of load nodes. And the effect of power sources access to the grid is also considered, which make the system of state vulnerability assessment to be more perfect to identify potential weaknesses of the grid. Combing the simulation results of IEEE-39 node system, it is verified the accuracy and superiority of the assessment model. In this way a theoretical reference is provided for the further study on reasonable planning power network and dispatching.
