[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the specification.
[0027] Such as figure 1 As shown, a method for power system restoration based on node importance includes the following steps:
[0028] 1) Calculate the regret value of the topological connectivity loss of the nodes in the power system and the regret value of the increase in the restoration cost of the nodes. The regret value of the topological connectivity loss of the nodes is the node pair that cannot be transmitted if the specified nodes are not restored after the power failure. The regret value of the increase in the restoration cost of the node is the increased restoration cost of the neighboring node through other paths if the specified node is not restored after the system is out of power;
[0029] 2) Calculate the importance of nodes based on the regret value of the topological connectivity loss and / or the incr...
