Wide-Area Transmission System Data Analysis and Visualization
Tom Overbye Texas A&M University [email protected]

Acknowledgments • Work presented here has been supported by a variety
of sources including PSERC, DOE, ARPA-E, NSF, EPRI, BPA, llinois Center for a Smarter Electric Grid and PowerWorld. Their support is gratefully acknowledged!
• Slides also include contributions from TAMU and UIUC graduate student and engineers including Komal Shetye, Sudipta Dutta, Saurav Mohapatra, Trevor Hutchins, Adam Birchfield, Ti Xu, Kathleen Gegner, and Iyke Idehen
• Thanks for human factor aspects from Prof. Esa Rantanen, Rochester Institute of Technology

Overview • Power system operations and planning are generating
more data than ever – In operations thousands of PMUs are now deployed – In planning many thousand of studies are now routinely run,
with a single transient stability run creating millions of values
• How data is transformed into actionable information is a crucial, yet often unemphasized, part of the software design process
• Presentation addresses some issues associated with dealing with this data
3
Visualization Software Design • Key question: what are the desired tasks that need to
be accomplished? – Needs for real-time operations might be quite different than
what is needed in planning
• Understanding the entire processes in which the visualizations are embedded is key
• Software should help humans make the more complex decisions, i.e., those requiring information and knowledge – Enhance human capabilities – Alleviate their limitations (like adding up bus flows)
4
Power System Operating States • Effective data analysis and visualization for operations
requires considering the different operating states
• Effective visualization is most needed for the more rare situations and for planning

Synthetic Models and Visualization • Access to actual power grid models is often restricted,
and this can be a particular concern with data analysis and visualization since its purpose is provide insight into the model, including weaknesses – Models cannot be freely shared with other researchers, and
even presenting results can be difficult
• Solution is to create entirely synthetic (fictitious) models the mimic the characteristics of actual models – We are doing this on an ARPA-E project, with all models
containing geographic coordinates
6
Synthetic Texas Model with 2000 Buses • ERCOT geographic
footprint • Four voltage levels:
500, 230, 161, 115 kV • 1250 substations,
2000 buses, 545 gens 2350 branches, 67 GW
• Geographic coordinates are available for all substations; model is now fully public at https://electricgrids.engr.tamu.edu

This is a synthetic power system model that does NOT represent the actual grid. It was developed as part of the US ARPA-E Grid Data research project and contains no CEII. To reference the model development approach, use:

Next Up: Ten Thousand Bus Case 8
• Model has 10K buses, 4700 substations, 16 areas, six nominal transmission voltages (765, 500, 345, 161, 138 and 115kV); total peak load is 150GW
• Green arrows show initial MW flows
• Model should be publicly available soon!
Background: Preattentive Processing • Good reference book: Colin Ware,
Information Visualization: Perception for Design, Third Edition, 2013
• When displaying large amounts of data, take advantage of preattentive cognitive processing – With preattentive processing the time spent to find a
“target” is independent of the number of distractors
• Graphical features that are preattentively processed include the general categories of form, color, motion, spatial position

Use of Color • Some use of color can be quite helpful
– 10% of male population has some degree of color blindness (1% for females)
• Do not use more than about ten colors for coding if reliable identification is required
• Color sequences can be used effectively for data maps (like contours) – Grayscale is useful for showing forms – Multi-color scales (like a spectrum) have advantages (more
steps) but also disadvantages (effectively comparing values) compared to bi-color sequences

Techniques for Time-Varying Data • Need to keep in mind the desired task! • Tabular displays • Time-based graphs (strip-charts for real-time) • Animation loops
– Can be quite effective with contours, but can be used with other types of data as well
• Data analysis algorithms, such as clustering, to detect unknown properties in the data – There is often too much data to make sense without some
pre-processing analysis!
15
Time-based graphs • Graphs can be quite
helpful for showing exact values if no more than about ten individual signals are shown – In larger sets outliers may
be missed
• Showing more values can be helpful in identifying response envelope – Graph at left shows 2400
signals
16
Animation Example 17
GVDs for Interactive Visualization • One issue with visualization is deciding a priori on the
information to show • A solution is to use what we’re calling geographic
information views (GDVs) in which embedded substation latitude and longitude allows displays to be auto-created – The previous animation loop was an example in which the
substations, used to contour the frequency, had been automatically inserted
• Now essentially any power system field can be shown

Conclusion • We've reached the point in which there is too much
data to handle most of it directly – Certainly the case with much time-varying data
• How data is transformed into actionable information is a crucial, yet often unemphasized, part of the software design process
• There is a need for continued research and development in this area – Synthetic dynamics cases are needed to help provide input
for such research
