Smart Grid Cyber-Physical System: An Overview

This chapter gives an introduction to the Smart Grid cyber-physical system and the various attacks that can be injected into the grid at various levels. The introduction of automation and control improves the grid stability and performance but also gives rise to various attack points. The power system is built to transmit data at a very fast rate and due to this speed requirement the security features such as encryption and key management are often not available for grid protocols such as DNP3, MODBUS, and IEC-61850.
