Progress in Microgrid (MG) research has evolved the MG concept from classical, purely MG power networks to more advanced power and communications networks. The communications infrastructure helps control and manage the unreliable power outputs that most standard power generation elements of the MG (e.g., wind turbines and photo-voltaic panels) deliver. Although communication technologies do offer certain advantages for sensing and control, they generate other complications due to packet loss and packet latency, among other transmission impairments. In this work, we discuss the impact of communications on MG performance, establishing the requirements of data exchanges and system response in the three levels of a hierarchical control approach: primary, secondary, and tertiary. With a focus on the secondary level-responsible for ensuring the restoration of electrical parameters-we identify standards, networking protocols, and communication technologies relevant for the interoperability of MGs and clusters of MGs, including both modes of operation: isolated and grid-connected. We review theoretical approaches and practical implementations that consider the effects of the communications network on the general performance of the MG. Moreover, we undertake an experimental analysis of the influence of wired and wireless communication networks on MG performance, revealing the importance of designing future smart control solutions more robust to communication degradation, especially if wireless technologies are integrated to provide scalable deployments. Aspects such as resilience, security, and interoperability are also shown to require continuing efforts in research and practical applications.

“…Otuoze et al [53] classified smart grid cyber vulnerabilities across technical (e.g., device and network) and non-technical (managerial and regulatory) issues. Mehrdad et al [54] surveyed cyberphysical security issues of smart grids across four dimensions of resiliency, including prevention and planning, detection, response, and recovery. Liu et al [55], Gunduz et al [56], and El Marabet et al [57] surveyed smart grid attacks based on emerging privacy and security requirements of smart grids, i.e., an equivalent taxonomy of the STRIDE threats.…”

With the roll-out of electric vehicles (EVs), the automobile industry is transitioning away from conventional gasoline-fueled vehicles. As a result, the EV charging demand is continuously growing and to meet this growing demand, various types of electric vehicle charging stations (EVCSs) are being deployed for commercial and residential use. This nexus of EVs, EVCSs, and power grids creates complex cyber-physical interdependencies that can be maliciously exploited to damage each of these components. This paper describes and analyzes cyber vulnerabilities that arise at this nexus and points to the current and emerging gaps in the security of the EV charging ecosystem. These vulnerabilities must be addressed as the number of EVs continue to grow worldwide and their impact on the power grid becomes more viable. The purpose of this paper is to list and characterize all backdoors that can be exploited to seriously harm either EV and EVCS equipments, or power grid, or both. The presented issues and challenges intend to ignite research efforts on cybersecurity of smart EV charging and enhancing power grid resiliency against such demand-side cyberattacks in general.

“…There have been a sufficiently large number of cyber attacks on energy facilities. Data attacks are the most common group of cyber attacks threatening the energy system security [2]. There are three main types of attacks on the data: False Data Interference (FDI), Load Redistribution Attacks (LRA), and Denial of Service/Distributed Denial of Service (DoS/DDoS) attacks.…”

A digital substation is an example of a cyber-physical system that is a sophisticated system consisting of two closely interrelated subsystems: physical (technological) and information-communication ones. Sophistication and vulnerability of an information-communication subsystem that performs functions of management becomes comparable to those of a physical subsystem. In the latest years the studies have been focused on the problems of cyber attacks against information-communication subsystems as potential external disturbances of present-day cyber-physical systems. Resilience is ability of an informational system to survive in the conditions of continuous cyber attacks. The proposed here approach to assessment of digital substation resilience using an event tree can serve as expert's assistance in ensuring the digital substation resilience.
