Abstract

The increasing digitalization of power systems has underscored the critical need for reliable communication, security, and advanced simulation tools in modern substations. This thesis presents a comprehensive investigation into key aspects of IEC 61850-based communication, cybersecurity, and real-time simulation, with a focus on improving system efficiency, resilience, and innovation. A thorough review and analysis of IEC 61850 communication protocols have been conducted, highlighting the significance of Generic Object-Oriented Substation Events (GOOSE), Manufacturing Messaging Specification (MMS), and Sampled Values (SV). These protocols play an essential role in ensuring reliable and time-sensitive communication between Intelligent Electronic Devices (IEDs) within digital substations, ultimately enhancing the automation and interoperability of power systems. The research further explores the application of real-time simulators in both academia and industry, emphasizing their benefits in bridging theoretical knowledge with practical applications. Real-time simulators provide a cost-effective means to optimize engineering processes, facilitate decision-making, and accelerate technological advancements. This research specifically focuses on the development and utilization of the Victoria University Zone Substation (VUZS) simulator, a robust testing facility designed to emulate real-world power system conditions. The VUZS simulator enables in-depth testing of communication protocols and cybersecurity measures, fostering collaborative research between Victoria University (VU) and Japan’s renowned public research institution, Fukushima Renewable Energy Institute (FREA). A key component of this research is the cross-border collaboration between VU and FREA, which enhances knowledge exchange and access to cutting-edge technologies. This partnership has significantly contributed to the advancement of digital power system research, strengthening global efforts toward more secure and efficient energy infrastructure. Cybersecurity remains a pressing challenge in IEC 61850-based systems, necessitating the integration of IEC 62351 security standards. This research further examines the implementation of IEC 62351 measures to ensure the integrity and confidentiality of substation communication, mitigating potential threats to the grid. Additionally, real-time simulators are leveraged to simulate cyberattack scenarios, allowing for a controlled analysis of system vulnerabilities. By assessing the effectiveness of various defense strategies, this research provides valuable insights into enhancing grid resilience against emerging cyber threats. In conclusion, this research contributes to the advancement of digital substations by addressing communication, cybersecurity, and simulation challenges. The findings offer practical solutions for academia and industry, paving the way for more secure, efficient, and resilient power systems.
