Conclusions
1. WAMS is a tremendously promising technology for control researchers
2. Control + Communications + Computing (CPS) must merge
3. Plenty of new research problems – EE, Applied Math, Computer Science
4. Plenty of new distributed optimization and control problems
5. Both theory and testbed experiments must progress
6. Right time to think mathematically – Network theory is imperative electric grid
7. Needs participation of young researchers!
8. Promises to create jobs and provide impetus to power engineering
