The invention discloses a multi-dimensional key node identification method and a multi-dimensional key node identification system for a sea island micro-grid group, and the method comprises the steps: obtaining basic information of the sea island micro-grid group; the nodes of the island micro-grid group are comprehensively evaluated from six dimensions of node local support capability evaluation, node global support capability evaluation, node operation performance evaluation, node robustness evaluation, node control performance evaluation and node coverage range evaluation; and then, on the basis of evaluation results of six dimensions, evaluation values of the nodes are calculated by using a fuzzy evaluation method, so that importance of all the nodes is obtained, identification of the key nodes is completed, and the problem that an existing island micro-grid group key node identification method neglects comprehensive evaluation of a distributed power supply and cannot identify the key nodes is solved.
