Research on the Relation of the Risk and Resilience Factors of Power Infrastructure

This paper deals with the resilience of power infrastructure. It studies the composition and mutual influence mechanism of the risk and resilience factors of power infrastructure. The natural, technical and man-made hazards that affect the power infrastructure are analyzed. The resilience elements and properties of power infrastructure are then built, from the aspects of engineering, economy, organization and environment. Using questionnaire surveys, a mathematical model for the mechanism of power infrastructure risk and resilience factors is developed. The resilience evaluation of power infrastructure is performed, and the built resilience model is verified using calculation examples. The results show that the proposed power infrastructure resilience evaluation model can efficiently evaluate the resilience of power infrastructure, and can be applied in several application domains.
