Abstract:As a method that utilizes the self-similarity property to analyze irregular objects,fractals can quantitatively process the geometric features of research objects,thereby making data analysis and planning more intuitive.This paper first introduces the definition and classification of fractals,and analyzes the connections and differences between different fractals.Then,based on the differences in the properties of objects described by fractals,from the perspectives of geometric fractals and algebraic fractals,the current application status of fractals in different fields of the power system is summarized,and several problems faced in application research are evaluated.Finally,the application of fractals in the power system is summarized.
