Problems of implementation, setup and cybersecurity of digital substations

Abstract

Introduction. The modern energy infrastructure is outdated, which threatens the reliability and quality of electricity supply. Aging infrastructure and operation at the limit of capabilities emphasize the need for modernization through the introduction of advanced equipment to improve the efficiency and reliability of energy supply. The introduction of digital substations using the IEC 61850 standard seems to be a promising solution that can improve the efficiency and reliability of energy supply.Goal. Research of proposals for the development of digital substations based on the IEC 61850 protocol and identification of areas for improvement in this area, with special attention to protection against cyber-attacks.Materials and methods. Methods of analyzing current standards and advanced technologies, such as IEC 61850, are used for a comprehensive study of digital substations. The role of the standard in ensuring the compatibility of automation and relay protection devices is analyzed. The study is based on an analysis of the work of domestic and international experts in the field of energy and cybersecurity. Results and discussion. The possibilities and problems associated with the integration of distributed energy resources and small-scale generation networks, as well as cybersecurity issues, are analyzed. Digitalization of substations helps to reduce installation and operation costs, improves the quality and reliability of energy supply. The development of comprehensive cyberattack protection systems to ensure network security plays an important role.Conclusion. Based on the results of the study, it can be concluded that the transition to digitalization of substations based on IEC 61850 can significantly reduce installation and operation costs, improve the quality and reliability of energy supply. The study highlights the need for further development and adaptation of digital substations, given the growing dependence on digital technologies in the energy sector. However, it is important to ensure cybersecurity and develop comprehensive protection systems that can withstand cyberattacks and ensure the security of small-scale networks.
