Abstract：Natural disasters have caused tremendous losses to the power grid in recent years. Now the urgent need of research on risk assessment in urban electric power network planning is how to scientifically assess the socio-economic impact on the city power and the society. Firstly, the damage and impact of power grid caused by natural disasters are summarized in this paper; then risk assessment model about the probability of occurrence of natural disasters and the impact on grid is established based on the information diffusion theory. Results of the case study prove that the proposed method can be suitable to adopt in risk assessment and provide a basis for decision of urban network planning considering the natural disaster risks.
