Sensitivity Analysis of Distribution Network Outage Impact Based on Ubiquitous Information

Based on ubiquitous information data, combined with historical operation data, considering several main factors such as network structure, operation and maintenance management level, equipment level and so on, this paper constructs a non-linear mapping relationship between input characteristic variables and reliability index value of fault outage, and analyzes each area of a certain area by using relevant variable detection method based on average influence value The importance difference of reliability influencing factors for different reliability indexes reflects the sensitivity of each factor relative to different reliability indexes; the sensitivity analysis of the impact of power failure on a city’s distribution network is carried out to obtain its weak links and provide reference for its reliability improvement direction.
