“…Liu et al consider attackers with full access to communication signals of MGs able to cause delays [13] and denial-of-service (DoS) attacks [19]. Similarly, Zhou et al assume attacks on MG communications links as well as local and master controllers where adversaries could interrupt any signal with full knowledge and access [15].…”

The distributed generation capabilities of microgrids (MGs) arise as essential assets in enhancing grid resilience. The integration of distributed energy sources (DERs), controllable loads, and prosumers necessitates the deployment of potent control and communication synergies. While those synergies transform MGs into cyber-physical systems through information technologies able to sense, control, and actuate local resources and loads, they inadvertently expose MGs to cyber-attack threats. Increasing the security of critical communication and control systems against 'black swan' events, i.e., high-impact lowprobability cyber-physical incidents, is a major priority for MGs operations. Such incidents, if left unabated, can intensify and elicit system dynamics instability, eventually causing outages and system failures. In this paper, we develop an integrated approach for multi-agent MG systems able to perform the detection of malicious cyber-physical attacks based on subspace methods. We employ the small signal model of an autonomous/islanded MG and consider different attack models targeting the MG's secondary frequency control. The attack detector is constructed via identifying the stable kernel representation of the autonomous cyber-physical MG in the attack-free case. We illustrate the impact of the attack models as well as the feasibility of the developed detection method in simulation models of the Canadian urban benchmark distribution system.

“…Resilience is topical in this field. A cyber-attack resilient control strategy for islanded microgrids is presented in Reference [46]. The proposed control strategy realizes the detection and isolation of corrupted communication links and controllers in a microgrid whose secondary control is based on a distributed control system.…”

Microgrids are growing in importance in the Smart Grid paradigm for power systems. Microgrid security is becoming crucial since these systems increasingly rely on information and communication technologies. Many technologies have been proposed in the last few years for the protection of industrial control systems, ranging from cryptography, network security, security monitoring systems, and innovative control strategies resilient to cyber-attacks. Still, electrical systems and microgrids present their own peculiarities, and some effort has to be put forth to apply cyber-protection technologies in the electrical sector. In the present work, we discuss the latest advancements and research trends in the field of microgrid cybersecurity in a tutorial form.
