In particular, it (1) reviews the state-of-the-art microgrid electrical systems, communication protocols, standards, and vulnerabilities while highlighting prevalent solutions to cybersecurity-related issues in them; (2) provides recommendations to enhance the security . This paper provides a comprehensive review of microgrid cybersecurity. The mitigations discussed herein specifically focus on cyber security technical requirements for the De-centralized Autonomous Community Controller (DAC) as part of the SECURE. Key Points Growing Cyber Risk in Microgrids: The distributed nature, two-way data flows, and device diversity in microgrids greatly expand the attack surface, making traditional perimeter-based security insufficient. This flexibility enables customer-level resilience and reliability improvements during extreme event outages and also reduces utility costs during normal grid operations. If microgrids are to become ubiquitous, it will require advanced methods of control and protection ranging from low-level inverter controls that can respond to faults to high-level multi-microgrid coordination to operate and protect the system. Microgrids are inherently dynamic systems due to their.
