Energy transition poses significant challenges, as the road ahead is focused on integrating higher share of renewables, promoting a more efficient and decentralized energy system, by involving advanced digital technologies and systems such as smart devices, faster and more flexible gateways, smart meters and IoT. However, this transition necessitates the integration of cyber-defense measures and strategies into novel, resilient and self-healing architectures.
The forthcoming smart energy ecosystem is considered as the next-generation power system, which promises self-healing, resilience, sustainability and efficiency to the critical energy infrastructure. However, due to the increasing digitization of the energy infrastructure, the risk of cyberattacks has risen dramatically, while as the smart energy and power grid is reaching every house and building, the potential of attracting cyber-attackers is magnified. Additionally, legacy systems constitute weak points of failure since they were designed in times when cybersecurity and remote monitoring and control was not part of the technical specifications for the system design.
