The invention relates to the technical field of network security, and discloses a power network dynamic defense system based on intelligent decision, comprising an attack monitoring module used for storing an attack monitoring strategy constructed according to attack feature data of a power network; the defense strategy library is used for storing and executing linkage defense strategies matched with the alarm information; the intelligent decision module is used for matching a plurality of target linkage defense strategies from a defense strategy library according to the target alarm information, generating a network attack graph by combining the target linkage defense strategies, the target alarm information and preset network information, and calculating and outputting a corresponding total network risk value when the linkage defense strategies are executed according to the network attack graph, according to the method, the total network risk value obtained by combining the network attack graph can reflect
