Power Grid Vulnerability Research Based on the Comprehensive Parameter

Abstract:

One of the main reasons caused the blackout accident is the existence of the power grid vulnerable unit. Therefore, how to find out the existing vulnerable unit accurately becomes a hot topic in the power grid at present. In this article, the problem aiming at the insufficient of grid vulnerability metrics is studied. Firstly, the new comprehensive vulnerability indicator was constructed to remedy the disadvantages of the current indicators of grid vulnerability. Secondly, the calculation process was listed. Finally, the advantages and disadvantages of the new indicator and the traditional indicator were analyzed in detail in the IEEE typical example. The result of the example shows that the new indicator built in this article is valid.
