Abstract:

Electric networks are globally significant systems being transformed to support increased wind and solar generation. Operating such networks requires managing not just components but weather, fuel, power flow, stability, operability, reliability, and more. To structure development of real-time operator support, we developed a conceptual model of electric transmission network operation that represents physical, functional, and purposeful distinctions and summaries used by experts at a North American transmission operator and reliability coordinator. The model scope includes 193 concepts at multiple levels of abstraction and scale, related in psychologically relevant terms according to the work domain analysis (WDA) theoretic framework. To manage this scale, we used both conceptual and topological decomposition, and linked prototypical examples to specifics of particular power grids. Figures in this article are accompanied by a web-browsable interactive digital supplement to navigate, interrogate, and review this model. We applied this model to human performance improvement projects including aligning conventions for technical visual communications and designing novel grid operational overview displays. This WDA provides a complementary perspective to grid ontologies proposed as knowledge models for future intelligent grid control systems.
