Excellent book! Intro by J. Glenn
Our Goal is to be the Greatest (but boring)

Equipment→Analysis→Models→Data→Simulation→Information→Analysis→Knowledge
Maybe Wisdom!?
This pyramid, although correct, needs to be inverted to properly convey our industry. But firstlet’s look at the Army’s view. Yes, the military has excellent examples of thought leadership. Anyoneknow why?
The Utility ArchetypeParadigm is so over used! ☺

This pyramid, although correct, needs to be inverted to properly convey our industry. But firstlets look at the Army’s view. Yes, the military has excellent examples of thought leadership. Anyoneknow why?
War is utterly Darwinian. There is no other human endeavorwith such a vicious and final feedback loop.
The Utility ArchetypeParadigm is so over used! ☺

Military operations are where Darwin rules
Mistakes kill in war! Data is KEY!
– Get it
– Transform it
– Understand it
– Analyze it
– Simulate it

Modeling and Simulation requires data
– The step-child of Planning
– Generally the ”newby”
– Often not a career track
– Technical! Not taught in school
– It matters…immensely
• Reworks caused by “bad” data
• Faulty premise leads to faulty decisions
– BS squared rule
– FAC & MOD violation
Data…the Inverted Pyramid

Data
The new guy/new girl is down here shoveling things they never were formally educated about
Proprietary and Confidential
Specifically our uses are modeling and simulation Humans lack the mathematical capacity to efficiently/effectively perform power
flows, short circuit, transient stability ,etc. simulations in our heads.
What do we use data for?
Westinghouse analog computerModeling and simulation was physical in those days.

We Want This
Proprietary and Confidential
And it comes from this stuff…

What this all looks like
Proprietary and Confidential
Good data vs.. bad (data matters!) Get it right! 1996 was a watershed moment
– We are still trudging forward
– Never retaining educated staff…
– Document!
Be Boring!!! No fines!!!
Why: Classic WSCC (now WECC) Slide from 1996

We are better now (WECC SRS Chair activities)

How: Very honest & points remain relevant

Irony is a WECC thing (SADD)… 42 is what? SADD metrics are >15K

2011 Az to CA Outage response
– WECC RC services split off
– WECC TSS led technical response
– Play well with others
Interoperability

Data Matters!
– Perhaps not “sexy”…or maybe it’s a huge opportunity (see last slide)
Outages are NOT desirable and will cause decades of pain
– Not the full employment plan you seek
Be impatient!
– Why tolerate utility inverse dog years
• 7 calendar years equals 1 utility year
Force software suppliers to play well together
– Kindergarten rules!
The industry needs well trained graduates on this subject
– Industry support to universities will help students learn about the tools and problems
