9th International Workshop on Electric Power Control Centers

Ullensvang, NorwayJune 11, 2007

This work was performed under contract with the Center for Grid Modernization, operated for U.S. DOE by Concurrent

Technologies Corporation (CTC)

Motivation

• Last decade has been a time of tremendous advances in area of power system visualization– Color contours, animated flow arrows, dynamical graphical

elements are now common on wide-area visualizations– These approaches are particularly effective for monitoring

• Such approaches are less useful when the task switches to corrective control

• Approaches are also less useful for engineering analysis

PSERC

Predefined graphical one-lines: Advantages and Disadvantages

• Advantages– Can be quite effective for monitoring large regions– Provide a consistent view of system– Can be panned and zoomed for more detail

• Disadvantages– Can become cluttered, and hence slow– Cannot be setup a priori to show all desired info

– Difficult to show information needed for control

• New technologies supplement, rather than replace the older ones

PSERC

My Own Experience: Developing Case for Human Factor Testing

• Goal was to develop a TVA and vicinity case for human factor testing

• Starting point was NERC MMWG 43,000 bus model with one-line showing high voltage grid–One-line had full geographic representation–Display performance was relatively slow–My frustration was even though I knew I had

the necessary data, I couldn’t see what I wanted to see

Solution Approach

• Since case already contains geographic information, insight was to dynamically create visualizations showing the information I was interested in, within a geographic context

• We are calling this approach “Geographic Data Views”–Key idea is to combine power system

information with underlying geographic model

Embedded Geographic Coordinates

• Embedded geographic coordinates could be–the actual location of the device; this has advantage

of allowing easy combination with other GIS information (like weather), but makes for crowed urban areas on wide-area displays

– a pseudo location as is common on many power system map displays; better display layout, but cannot be easily combined with GIS information

–both, with specific values selected when the visualization is created or morphed between them

PSERC

Power of Approach Becomes More Apparent With Embedded GDVs

• One common reliability coordinator task is the re-dispatch of generation to remove line overloads (usually contingent overloads)

• This task requires a combination of information about the available regulation range for the generator, along with its sensitivity with respect to the violation

16

PSERC

Sensitivity of Line Flow to Change in Generation

• The sensitivity of the line flow to a change in generation can be easily calculated provided topology information is available

[ ] 1−=Δθ B' ΔP

Next slide shows an earlier attempt at visualizingthese control sensitivities

17

PSERC

8/14/2003 Example: Sensitivity of Sammis-Star Flow to Injections

But valuesare linedependent,so makingcalculationeasy isvery important

18

PSERC

Embedded GDV Approach

• Information about available generation and their line flow sensitivities can be shown via an embedded geographic data view

• Dialog is accessed by right-clicking on overloaded element

19

PSERC

Display of Colored “Kites” to Show Available Generation and Sensitivities

Kites arevertically symmetric quadrilateralsformed bymerging anupward pointing isosceles triangle witha downwardpointingone

PSERC

Moving Forward

• GDVs work well in a task-oriented approach• GDV representation of information could be

useful whenever–A geographic representation could be beneficial–And precise numeric\ values are not required

• Approach can be useful for the display ofbothactual data and derived data

• Most control center applications would fit, as would many engineering applications
