A Novel Cyber-physical Distribution Network Security Analysis and Evaluation Strategy Based on Correlation Characteristic Matrix

With the further integration of cyber communication network and physical model of electrical equipment in the distribution network, cyber-physical combined faults have become a difficult problem and caused system security deterioration. To solve this problem, this paper established the cyber-physical fusion model of distribution network from two aspects of both cyber and physical layer. In this paper, the safety performance of distribution network cyber physical system (CPS) is analyzed by the proposed correlation characteristic matrix, based on which a complete CPS safety evaluation method is presented, and the effectiveness of the proposed method is verified by a typical IEEE-62 example.
