With the improvement of information level, the information attack will cross the boundary of power grid information space and cause the disturbance of power grid physical system, which will form a cross-space chain fault and affect the safe operation of power grid. Based on this, this paper proposes a distribution network node risk assessment method based on information physical fusion. Firstly, the overall structure of the distribution network and the information physical coupling characteristics of the information physical fusion are studied. Then, the cross-space chain failure scenario of distribution network with information physical fusion is analyzed. Based on this, the risk assessment method is proposed. Finally, the effectiveness of the method is verified by a numerical example.
