Abstract
Cyber threats pose an increasing threat to energy objects. It is essential to ensure the cybersecurity of automatic control systems, such as relay protection devices (RP), devices of regime control (RC) and emergency control (EC), automated control systems. At the same time, the issues of cybersecurity include not only the problem of hacker attacks, but also the whole complex of problems relating to adequate functioning of cybernetic systems in the power industry. The authors propose a methodical approach to the analysis of the structure of automatic means of regime and emergency control in terms of their impact on the reliability and survivability of power systems (EPS), taking into account the known threats to cybersecurity.
Highlights
There have been active discussions on the topic of digital substations and the implementation of solutions for the power industry based on IEC 61850, these discussions take place against the background of the process of introducing these technologies to power objects
Russia has begun to open the active discussion about total digitalization and digital transformation of the power industry while taking practical steps towards said digitalization [1,2,3,4]
It is of great importance to ensure the cybersecurity of automatic control systems, such as relay protection devices, devices of regime and emergency control, automated control systems [6]
Summary
There have been active discussions on the topic of digital substations and the implementation of solutions for the power industry based on IEC 61850, these discussions take place against the background of the process of introducing these technologies to power objects Participating in these discussions, the authors repeatedly noted the presence of the problem of cybersecurity in the mass introduction of digital substation technologies. Russia has begun to open the active discussion about total digitalization and digital transformation of the power industry while taking practical steps towards said digitalization [1,2,3,4] In these conditions, the urgency of the problem of cybersecurity has significantly increased. It is important to pay attention to the influence of reliability and cybersecurity of digital subsystems on the overall reliability of power objects, EPS and their associations [7]
