Resilient, Cyber Secure Centralized Substation Protection
Project Innovation + Advantages:
The Georgia Tech Research Corporation will design an autonomous, resilient and cyber-secure protection and control system for each power plant and substation on its grid. This will eliminate complex coordinated protection settings and transform the protection practice into a simpler, intelligent, automated and transparent process. The technology will integrate protective relays into an intelligent protection scheme that relies on existing high data redundancy in substations to (a) validate data; (b) detect hidden failures and in this case self-heal the protection and control system; (c) detect cyber-attacks (focus on false data and/or malicious control injection) and identify the source for attribution; and (d) provide the full state of the system with minimal delay for optimal full state feedback control.
The proposed technologies simplify grid protection by eliminating the need for coordination, lessening relay misoperations, and enabling detection and self-healing against cyber attacks and hidden failures.
A protected grid would be more resilient to disruptions from equipment failure, natural disasters, or attack.
