As a national critical infrastructure, the smart grid has attractedwidespread attention for its cybersecurity issues. The development towards anintelligent, digital, and Internetconnected smart grid has attracted externaladversaries for malicious activities. It is necessary to enhance itscybersecurity by either improving the existing defense approaches orintroducing novel developed technologies to the smart grid context. As anemerging technology, digital twin (DT) is considered as an enabler for enhancedsecurity. However, the practical implementation is quite challenging. This isdue to the knowledge barriers among smart grid designers, security experts, andDT developers. Each single domain is a complicated system covering variouscomponents and technologies. As a result, works are needed to sort out relevantcontents so that DT can be better embedded in the security architecture designof smart grid. In order to meet this demand, our paper covers the above threedomains, i.e., smart grid, cybersecurity, and DT. Specifically, the paper i)introduces the background of the smart grid; ii) reviews external cyber attacksfrom attack incidents and attack methods; iii) introduces critical defenseapproaches in industrial cyber systems, which include device identification,vulnerability discovery, intrusion detection systems (IDSs), honeypots,attribution, and threat intelligence (TI); iv) reviews the relevant content ofDT, including its basic concepts, applications in the smart grid, and how DTenhances the security. In the end, the paper puts forward our securityconsiderations on the future development of DT-based smart grid. The survey isexpected to help developers break knowledge barriers among smart grid,cybersecurity, and DT, and provide guidelines for future security design ofDT-based smart grid.
