Research on Heterogeneous Characteristics Index of Complex Power Grid Based on Information Entropy Theory

Abstract

The non-homogeneous characteristics of complex power grids have a boost to the occurrence of large power outages and chain failures, and in order to more accurately characterize the non-homogeneous characteristics of complex power grids, this paper constructs the topological entropy of the power grid and the trend entropy of the power grid based on the theory of information entropy, and makes a comparative analysis with the Gini coefficient. Using the flow entropy of the power grid and the entropy of the power grid topology to characterize the nonhomogeneous characteristics of the complex power grid in the trend distribution and the structure of the grid frame, it is more intuitive, accurate and reasonable.
