Emergency capability evaluation of power systems under extreme weather conditions based on cloud D-S evidence theory
This article aims to improve the ability to respond to power system emergencies under extreme weather conditions,the emergency response capability of power system is taken as the research object,and an evaluation algorithm based on the fusion of cloud models and evidence theory is proposed.The combination of analytic hierarchy process and entropy method are used to determine the weights of emergency indicators,the cloud model is used as the basis to evaluate the emergency capacity of the power system,which is used to solve the problems of fuzziness and randomness of evaluation indicators,and the D-S evidence theory is introduced to comprehensively evaluate the indicators,and then a model for evaluating the emergency capacity of the power system under extreme weather conditions is constructed.It is proved through cases that this method can effectively and accurately evaluate the emergency capability of power grid systems quantitatively and qualitatively,and provide a scientific basis for improving the emergency management capability of power grid systems.
