What Are We Trying to Achieve?
EPRI’s Research Objective
• To improve the situational awareness of control center operators when operating the increasingly complex and evolving transmission system of today and tomorrow
Objective for Utilities
• How do we define the information operators need in real time for the evolving system?
• How do we present the information to operators?
• How do we make it easy for the operators to affect change based on the information received?
Objective of this Session
• Discuss an approach to work domain analysis developed by EPRI for a transmission operator in the US, building on previous work for IESO. Discuss how this can be applied to display design, alarm management, situational awareness

Context of Work Domain Analysis Efforts
Ecological Interface Design
• Work Domain Analysis developed by Rasmussen et al. 1980s
WDA for IESO
• Hilliard, Tran Jamieson developed a WDA for IESO Ontario
WDA for Duke Energy TOP
• EPRI Case Study 2019
• Specific to Transmission Operations as defined by NERC

Next Steps
▪ Define a WDA for a Balancing Authority, Reliability Coordinator, Security Coordinator, Distribution System Operator
▪ Extend or improve the abstraction hierarchy. Incorporate skills, time, relationship to situational awareness, mental workload?
▪ Seek industry and vendor feedback
▪ Design dashboards based on the WDA, in particular for PMU systems

EPRI Advanced Situational Awareness & AI in Control Center - Interest Group
Research Challenge
Research Requirements
The evolving system requires new information, data, tools, solutions, training, techniques. There is much we can learn from human factors research in other industries and apply to transmission. The hardware tools and AI algorithms are accessible and applicable.
Methodology
Advanced Situational Awareness – Derive the information requirements, map the information
flow, identify tools for monitoring situational awareness
Artificial Intelligence – Identify the tools, use cases, data flow for maximizing AI technology in control centers. Develop AI algorithms for use in
real time operations
The 2019 PlanEPRI to form an interest group of TSOs, SMEs for advanced situational awareness and AI in control centers.
Interest group will involve, knowledge share, webcasts, tool development, face to face meetings.
