摘要：In view of the AC-DC interconnected background, this paper studied the evaluation method of node importance during the grid restoration. Firstly, based on the constraints of DC transmission system start, the processing method for evaluating the electrical property of the converter station was proposed. Next, combined with generator and load capacity, the electrical property index of node was put forward. Then, two indexes were raised from different aspects of power-off network. Finally, with the help of CRITIC weighting method, the three indexes mentioned above were well integrated to identify key nodes. The example showed that this method could not only express the network topology information of the node commendably but also reflect electrical property effectively in current state. © 2019 IEEE.
