As new technology upends decades-long practices for managing the electric grid, the ability to exchange actionable information between devices and organizations is more important than ever. From grid-edge intelligence to customer-owned resources, evolving grid architectures will introduce complex dynamics that span physical, economic, and information technology aspects of electrical systems. Improved interoperability is critical to managing these complexities, and to facilitate that NIST revised its Framework and Roadmap for Smart Grid Interoperability Standards. First published in 2010 and developed in collaboration with the broad smart grid stakeholder community, this fourth version of the Interoperability Framework examines various communications pathway scenarios to understand impacts on grid cybersecurity, operations, economics, and associated requirements for testing and certification. This session will provide an overview of key concepts from the draft Framework chapters on grid operations, cybersecurity, economics, and testing and certification. Attendees are invited to review NIST's draft Framework and Roadmap for Smart Grid Interoperability Standards and provide feedback.
