Summary: | The invention discloses a grid overall vulnerability comprehensive evaluation method, which comprises the following steps: 1) inputting vulnerability index result data of each node in a power grid; 2) according to a clustering algorithm, carrying out clustering on the vulnerability index result data of the nodes in the power grid to obtain optimum classification number of node vulnerability grade; and 3) determining vulnerability mean value and vulnerability balance degree G in power grid overall vulnerability comprehensive evaluation index, and calculating the power grid overall vulnerability comprehensive evaluation index V. The method has the following advantages: through the power grid overall vulnerability comprehensive evaluation method, balance degree of power grid overall vulnerability distribution can be evaluated, and average vulnerability of the power grid can be evaluated.
