The security of communication protocols in the smart grid system is a crucial concern. An adversary can exploit the lack of confidentiality and authentication mechanism to cause damaging consequences. In the substation automation systems that rely on multicast communication between various intelligent electronic devices, the lack of security features in the standard IEC61850 and IEC62351 can invite attackers to manipulate the integrity of the employed publisher–subscriber communication paradigm to their advantage. Consequently, many researchers have introduced various approaches offering authenticity and confidentiality. However, such schemes and methods for the aforesaid standards have computational limitations in compliance with the stringent timing requirements of specific applications in the smart grid. In this paper, we propose an approach that can fully secure the publisher–subscriber communication against confidentiality attacks. In this direction, we develop a demo tool to validate the performance of our proposed security approach for potential factors such as timing requirements and the size of the messages. Finally, we evaluate our scheme considering the requirements of the GOOSE, SMV, and MMS protocols in the substation automation systems.
В статье рассматриваются наиболее часто используемые стандарты и протоколы интеллектуальных сетей для приложений, начиная от предприятий и центров управления до глобального мониторинга, автоматизации подстанций, распределенной генерации, реагирования на спрос, измерения.
This article discusses the most commonly used smart grid standards and protocols for applications ranging from enterprises and control centers to global monitoring, substation automation, distributed generation, demand response, metering.
This paper deals with Industrial Control Systems (ICS) of the electrical sector and especially on the Smart Grid. This sector has been particularly active at establishing new standards to improve interoperability between all sector players, driven by the liberalization of the market and the introduction of distributed generation of energy. The paper provides a state-of-the-art analysis on architectures, technologies, communication protocols, applications, and information standards mainly focusing on substation automation in the transmission and distribution domain. The analysis shows that there is tremendous effort from the Smart Grid key stakeholders to improve interoperability across the different components managing an electrical grid, from field processes to market exchanges, allowing the information flowing more and more freely across applications and domains and creating opportunity for new applications that are not any more constraint to a single domain.
With the acceleration of smart grid construction, intelligent become the development direction of the automatic substation, primary equipment is an important part of intelligent smart grid, running for safe and reliable operation of the substation automation is significant. This article briefly describes a device in the form of intelligence, once analyzed the working principle of intelligent devices and describes the intelligent transformers, circuit breakers and other primary equipment implementation.
