Abstract
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.
Highlights
Microgrids can be defined as small-scale, low, or medium voltage power systems with a decentralized group of electricity sources and loads, which can operate connected to or separated (“islanded”) from the main power network
This paper aims to discuss the main recent advancements and new research trends in the field of cybersecurity of smart microgrids, and the applications in this field of innovative technologies, such as Software Defined Networking, new approaches for intrusion and anomaly detection, and resilient control strategies
The drawback of using Software-Defined Networking (SDN) stands in the possible delay introduced by these actions, which could be incompatible with some actions required in an industrial environment
Summary
Microgrids can be defined as small-scale, low, or medium voltage power systems with a decentralized group of electricity sources and loads, which can operate connected to or separated (“islanded”) from the main power network. The electrical grid is a critical infrastructure, so it can be the target of attackers with huge technical and economical capacities For these reasons, cybersecurity is a fundamental issue to improve the resilience of microgrids. This paper aims to discuss the main recent advancements and new research trends in the field of cybersecurity of smart microgrids, and the applications in this field of innovative technologies, such as Software Defined Networking, new approaches for intrusion and anomaly detection, and resilient control strategies.
