Description
A key advantage of GDVs is that they can be used to visualize a wide variety of different power system field values with the ability to use different display attributes to simultaneously show different fields. However, visualization solutions also have certain drawbacks, and their development should therefore be done very carefully and with participation of the operators eventually using them. It is also clear that current GDVs are not appropriate for replacement of existing text-based and predefined object visualizations. Rather they should be implemented to supplement existing techniques, as major uses are expected in areas of power system analysis and corrective control particularly for wide-area visualizations. The ecologically valid GDV interface also allows for operator creativity in seeking solutions to line violations. Therefore, GDV displays warrant further research with respect to decluttering algorithms, optimal choice of colors and sizes of the visual elements, and provision of numerical raw data on demand
The GDV displays show power transmission lines and substations laid on a geographic map; consequently certain areas (e.g., in and around cities) become extremely cluttered. To reduce clutter, closely located substations could be spread out and transmission lines between them drawn, for example, in rectilinear pattern minimizing line overlaps and crossings. Such patterns optimized with respect to given constraints can be created by a number of operations research (OR) techniques.
The proposed research has three distinct phases: (1) to systematically evaluate different OR techniques and their outputs with respect to their ability to solve such large-scale problems, (2) to develop experimental displays, which are to include many other display innovations (cf. Rantanen, Winkle, & Overbye, 2008) than just the optimized layouts, and (3) to perform experiments using human subjects and realistic simulated scenarios to assess how different display layouts af
