![]() ![]() In addition, communication latency represents an important bottleneck for the controller speed, and its modelling and impact on the control are both of interest for the scientific community. ![]() However, the interactions between primary and secondary controllers when their bandwidths are close has not been addressed in detail in the literature. In general, different control layers are designed with sufficient bandwidth separation between them to avoid unwanted dynamic interactions, resulting in slow outer controllers. To coordinate the operation of these DERs, a three-level hierarchical control is commonly used. Microgrids (MGs) facilitate the integration of distributed energy resources (DERs) in electrical grids. Finally, some points regarding the role of cyber-security in the future of SGs are presented. The decisive problem-solving approaches and defense mechanisms are presented. The cutting-edge cyber security approaches such as blockchain and quantum computing in SGs and power systems are stated, and recent research directions are highlighted. Furthermore, the characteristics and applicability of different cyber-attack models are technically discussed and analyzed. In the first step, we discuss the interactive features of cyber-security then, their modeling and mechanisms are reviewed and summarized in detail. This paper aims to systematically summarize different methods and techniques and to review corresponding solution approaches in cyber-security in energy systems. Studying, analyzing and providing solutions to mitigate or solve these problems highly depend on accurate modeling methods and examining the interaction mechanisms associated with the cyber-security of Smart Grids (SGs). CPPSs confront newly emerging issues including stability, resiliency, reliability, vulnerability and also security. These structures usually have connections between power sections and cyber parts. ![]() 233–240, 2011.Due to the advancement in communication networks, metering and smart control systems, as well as the prevalent use of Internet-based structures, new forms of power systems have seen moderate changes with respect to several aspects of contradictory Cyber–Physical Power Systems (CPPSs).
