Risk Assessment Of Distribution Network In Chengdu Based On Entropy Weight

With the development of the national economy,society in the continuous progress,and the people's living standards are also improving,the user's demand for electricity quality is also getting higher and higher.Distribution network as the last link to connect users,is to ensure the quality of power supply key link.In order to be able to safely and reliably supply power,it is necessary to evaluate the risk status of the distribution network.First of all,this paper describes the risk assessment of distribution network at home and abroad,and compares the research status of distribution network risk management at home and abroad,and analyzes its status.The basic theory of risk management is introduced,and several commonly used risk assessment methods are introduced.The risk management and evaluation of distribution network are analyzed,and then the superiority and the possibility of the entropy weight element method is introduced into the distribution network risk assessment.This paper introduces the significance and principle of the risk assessment of distribution network,and establishes a multi-level and more scientific risk assessment index system based on the research results.Then,it establishes the physical and mechanical risk assessment system for distribution network.And the entropy weight method is used to calculate the weight of the index.This paper introduces the general situation of distribution network in Chengdu and analyzes the current situation of risk management of distribution network,and applies the entropy weight matter element model to Chengdu distribution network,and obtains the factors and overall risk of distribution network in Chengdu Value,which provides help for decision making.Finally,the paper puts forward some suggestions on the risk assessment of distribution network in Chengdu,and makes a prospect of the further research on the risk assessment of distribution network.
