A multi-level active security defense technology for smart microgrid flexible access to power system nodes based on mutation fruit fly optimization algorithm was proposed to address the issue of queue packet loss in data transmission between nodes during the process of smart microgrid flexible access to power system.Utilize the mutation fruit fly optimization algorithm to process historical data of attack behavior and actively detect attack behavior in the power system;identify dangerous events in the operation of the power system based on the detection results of attack behavior;on this basis,establish an active defense decision support architecture to execute corresponding security defense measures based on early warning information.The experimental results show that the proposed active security defense technology based on mutation fruit fly optimization algorithm has a high acceptance rate of node packets,a low loss rate of multi-level queue packets,and an improved effectiveness of the defense technology.
