DISTRIBUTED LEDGER TECHNOLOGY FRAMEWORK FOR POWER GRID INFRASTRUCTURE

This abstract first appeared for US patent application 20250062612 titled 'DISTRIBUTED LEDGER TECHNOLOGY FRAMEWORK FOR POWER GRID INFRASTRUCTURE

Original Abstract Submitted

an attestation framework to support attestation and anomaly detection in an electric grid. the attestation framework provides systems and methods that use distributed ledger technology (dlt) and implement dlt-based methods for verifying device and data trustworthiness on the electric grid. the framework attests to system changes and anomaly detection to flag specific events such as natural and cyber-induced grid events categorization, electrical faults in meters and relays and cyber events, e.g., based on statistical and baseline threshold values. the attestation framework can support the detection of system changes by itself, and in combination with an anomaly detection framework, has a lower system resource requirement and is more likely to catch system changes. an anomaly detection module can trigger attestation checks and uses the dlt for device and configuration verification purposes. the attestation framework can be deployed at substations or other environments, such as ders or a microgrid.
