A Hierarchical Color Net Model For Smart Grid Security Monitoring

摘要

Smart grids equipped with highly valuable components like intelligent electronic devices (IED), smart meters, etc. are replacing the traditional power grids. Smart grids are to depend heavily on ad-hoc, wireless networks and internet for communication. Hence these are quite prone to various types of physical and cyber intrusions. Meter tampering is also treated as intrusion. Intrusion on smart meters has become easier in the sense that no physical tampering of the device is required. Instead a smart hacker can corrupt the data being gathered and transmitted electronically. In this paper, a hierarchical Color net model has been proposed for power transmission and distribution from the main power station to the consumers. The proposed model detects any tampering of the smart meter data that occurs at consumer level and carries the security information (affected smart meter ids) to the higher level security servers where it can be tracked down and isolated.
