In the context of cyber-physical fusion, the impact of information system failures on system reliability has become a research hotspot. In order to improve the reliability of power supply in distribution network, a multi-objective planning method for switch and distribution automation terminals considering information system faults is proposed in this paper. First of all, a distribution network reliability calculation method is proposed considering information system faults. This method can adapt to different topologies and can quickly calculate the distribution network reliability. Then, a multi-objective programming model for switch and distribution automation terminals is established, which takes the investment cost and the average power supply shortage of the system as the goal. The improved non dominated sorting genetic algorithm II algorithm is used to solve the above model. The configuration schemes in the scenario of the IEEE-33 system are compared to verify the effectiveness of the proposed method.
