Abstract
This special section is devoted to the latest research advances in cyber-physical security and privacy of smart grids. A smart grid integrates advanced communication technologies and efficient bi-directional energy dispatch into the physical grid with the goal of achieving effective and efficient power management. However, the integration would make the mission-critical energy infrastructure more vulnerable to a wide variety of malicious cyber-attacks. Therefore, it is imperative to investigate the critical threats to the smart grid cyber-physical security and privacy, as well as to propose effective countermeasures to improve security and resilience of the smart grid.
