Abstract

Cyber-physical power systems (CPPS) are interconnected architectures that interact with the physical power system environment by utilizing communication, control, and computing resources. Enterprise, industries, and critical infrastructure rely on CPPS. As a result of their critical importance, they are prime targets for cyberattacks aimed at disrupting their operations. CPPS are mission-critical, attacks on them can have disastrous consequences. CPPS security can be improved by utilizing testbed capabilities to replicate power system operations, discover threats, develop sustainable cybersecurity solutions, and evaluate grid operation in physical fault-induced or cyberattack scenarios. This Part-II paper reviews the CPPS testbeds in the view of the testbed type, targeted research area, CPPS domain, and communication infrastructure with the fusion of physical and cyber systems. Furthermore, this review gives an outline, framework, and application-based assessment of various industry and institutional testbeds. The design process of CPPS testbeds is reviewed first in this paper(Part-II), followed by description of the classification of CPPS testbeds for cyberattacks and sustainable cybersecurity analysis in CPPS. A brief overview of CPPS testbeds in various academic institutions, R&D laboratories, and industries are provided and each testbed is evaluated using the eleven proposed assessment criteria. Finally, the current issues and future research directions for CPPS testbeds to develop a secure and sustainable electric power grid are discussed. The Part-I paper reviewed the major research areas in CPPS, the importance of cyberattack testbeds, and long-term cybersecurity analysis in CPPS, as well as the NIST framework for CPS, CPPS domains and research areas.
