Implementing Dynamic Line Rating: Key Considerations for Security and Reliability

The presentation begins with an Introduction to Dynamic Line Rating (DLR), explaining that DLR is a method to determine the real-time current-carrying capacity of transmission lines using environmental and operational data. It contrasts DLR with static line ratings, highlighting DLR's ability to adjust capacity in real-time based on current conditions, thus optimizing asset utilization and enhancing operational flexibility.

Reliability Considerations focus on ensuring data accuracy through sensor calibration, robust communication infrastructure, accounting for environmental uncertainties, and system redundancy. These measures are crucial for maintaining the reliability of DLR systems.

Cybersecurity Considerations address the threat landscape, including data confidentiality, integrity, and availability. It discusses common attack vectors such as Denial of Service (DoS), Man-in-the-middle (MITM), and data manipulation. The presentation emphasizes the importance of securing sensors, communication channels, and legacy systems.

The Integration of Cybersecurity and Reliability section highlights the need for data integrity, continuous operation, and balancing operational flexibility with cybersecurity measures. It underscores the importance of interdependency management.

The presentation concludes with Takeaways, emphasizing the need for a balanced approach that integrates technology, processes, and people. It also stresses the importance of continuous improvement, regular risk assessments, and adherence to regulatory standards.
