Considerations for Secure Data Exchange to Achieve Cyber-Physical Situational Awareness in the Electric Grid

Cyber-physical situational awareness (CPSA) is crucial for understanding the intricacies and relationships within the interconnected electric grid, especially with increasing distributed energy resource penetration. However, beyond developing the necessary cyber-physical data fusion techniques, another critical challenge to address is the multi-level, multi-owner data exchange process and its cybersecurity. Therefore, in this paper we explore the considerations for secure data exchange for performing CPSA analysis and present the current landscape alongside existing gaps, potential solutions, and next steps. Additionally, we present a case study related to the project team's CPSA sensor and implementation architecture development, called griDNA, and how these potential solutions could apply and form a secure data exchange framework.
