Grid Operation

Smart grids are becoming increasingly popular thanks to their ability to operate with higher precision and smaller margins. Dynamic operation control in smart grids can be achieved with phasor measurement unit (PMU) based wide area monitoring and control systems. The data communication requirements for the PMU based applications are well addressed in the IEEE C37.118.2 and IEC 61850-90-5 standards. Due to the higher probability of cyberattacks and the scale of their impact, data security is a critical requirement in PMU communication networks. The IEC 61850-90-5 communication standard addresses this security concern and proposes the HMAC (hash based message authentication code) with key distribution center (KDC) scheme for achieving information authentication and integrity. However, these IEC 61850-90-5 security recommendations do not consider the mechanism for attacks such as man-in-the-middle (MITM) attacks during KDC key exchanges. MITM attacks can be easily implemented and may have a large impact on the grid operation. This paper proposed an explicit certificate-based authentication mechanism to mitigate MITM attacks in PMU communication networks. The proposed certificate-based authentication mechanisms were implemented in real-time using Python-based terminals to observe their performance with different signature algorithms.

Este artigo apresenta medidas do workload obtidas em uma subestação que se encontra em meio à implantação do padrão IEC 61850 - Communication Networks and Systems in Substations, considerado vital para as redes inteligentes no domínio elétrico ou smart grids. A carga real auxiliará na avaliação dos requisitos da norma e planejamento de capacidade para processos decisórios. É necessário o monitoramento contínuo da rede de comunicação que atende o SAS (Sistema de Automação de Subestação) com suas especificidades, avanços e complexidades em vista de novos requisitos de gerenciamento e segurança no que tange à disponibilidade e confiabilidade. Busca-se contribuir com a análise de carga de dados operacionais com este enfoque integrado da rede de comunicação e a rede de supervisão em uma Subestação do Setor Elétrico.

Time Critical

Since the 1990s, the digitalization process has transformed the communication infrastructure within the electrical grid: proprietary infrastructures and protocols have been replaced by the IEC 61850 approach, which realizes interoperability among vendors. Furthermore, the latest networking solutions merge operational technologies (OTs) and informational technology (IT) traffics in the same media, such as time-sensitive networking (TSN)—standard, interoperable, deterministic, and Ethernet-based. It merges OT and IT worlds by defining three basic traffic types: scheduled, best-effort, and reserved traffic. However, TSN demands security against potential new cyberattacks, primarily, to protect real-time critical messages. Consequently, security in the smart grid has turned into a hot topic under regulation, standardization, and business. This survey collects vulnerabilities of the communication in the smart grid and reveals security mechanisms introduced by international electrotechnical commission (IEC) 62351-6 and how to apply them to time-sensitive networking.
