This paper proposes an active distribution system optimization planning method based on multi-agent consistency. Firstly, based on the mechanism of power information physical fusion system and non-ideal time-varying communication topology features in distribution network planning, the multi-agent active distribution system planning architecture is proposed. Secondly, the multi-agent system collaborative control method is introduced, and the communication delay multi-agent system with complex network environment with communication delay and attack behavior nodes is considered.The adaptive control method with adaptive ability is proposed. Finally, the simulation example is adopted. The effectiveness of the proposed method for the security of the active distribution system under communication delay and encountering malicious node attacks is verified. Moreover, through the voltage offset sensitivity test, it is verified that the information transmission quality has a significant impact on the physical system. The collaborative planning of the physical system and information system of the multi-agent active distribution system is beneficial to the safe and reliable operation of the distribution system, and the decision-making basis is provided for the optimization planning decision of the active power distribution system.
