Abstract
Internet of Energy (IoE) is one of the important concepts for facilitating technological, economic, and social development, helping people in their lives. The IoE paradigm encompasses solutions from generation units to loads, and one of its principal concerns is digitalized substations. The evolution of electrical energy systems through digitalized substations is mainly based on IEC 61850, allowing more efficient monitoring, control, automation, and protection systems. Despite the numerous benefits, this digitization brought cybersecurity challenges, mainly associated with the IEC 61850 GOOSE protocol. One of the most critical aspects of securing communication systems in digitalized substations is which mitigation method is more efficient for this specific and crucial scenario. Equally important, the security requirements, vulnerabilities, and solutions lack correlation. However, very few articles focus on this theme systematically, thoroughly, and unbiasedly; To our knowledge, none of these papers conducted a systematic review considering the security requirements for IEC 61850-based substations, presenting the vulnerabilities, attacks, and mitigation methods. This paper presents a systematic literature review from the first articles published in 2021 concerning cybersecurity methods and techniques. We summarize the pieces for this issue and provide a correlation between the security requirements, the attacks, mitigation methods, and security gaps to position new research activities appropriately.Pubblicazioni consigliate
