  1. Overview of EE 215 Electric Energy Systems AnalysisIE: Why you/everyone should take this class Paul Hines, Ph.D. Spring 2010

  2. Why should we study P.S. Analysis? • A bit of history • Sometimes stuff breaks: • Terrorists, wind, hurricanes, earthquakes, lightning, etc. • Sometimes power plants vary: • Wind and solar power • Power plant failures • Blackouts

  3. Nov. 9, 1965 30 million people affected! July 13, 1977 Widespread looting, chaos. >3000 arrests. Aug 14, 2003 50 million people affected! $2-10 billion economic costs NYC traffic paralyzed Italy, 2003 Several deaths (traffic lights & falls) Thousands stranded in transit Germany/France, Nov. 2006 >15 million affected Many trains stop. Major delays. “Europe came very close to a complete blackout.” –Bornard Brazil, Nov. 2009 50 million w/o power Famous large blackouts (remember these)

  4. 1. Cascading failures Hidden failure(s) Stress Agents react “selfishly” to stress Massive failure Changes in network structure Initial Disturbance

  5. 2. Frequent large failures Aug. 14, 2003 Solar flare, Quebec July 2, Aug. 10, West Number of blackouts larger than 300 MW

  6. 3. Power-laws in failure sizes Most infrastructure systems see very large failures more frequently than we would get from Gaussian statistics Air/road traffic, internet, finance, … Slope = -1.2

  7. 4. Wind Source: Jay Apt, CMU

  8. 5. Solar Source: Jay Apt, CMU

  9. Ch 2. Review of three-phase power

  10. Chs. 3-4. Transmission Lines

  11. Ch. 5, Transformers, Per unit normalization

  12. Ch. 6, 7, 8 Generator modeling

  13. Chs. 9-10. Network modeling and power flow

  14. Ch. 11. Automatic Generation Control • Keeping the balance between supply and demand • Simulink modeling

  15. Ch. 12. Unbalanced system analysis TAMU, Qatar

  16. Ch. 13, Relaying and protection • http://image.ec21.com/image/wuxihe/oimg_GC03309082_CA03309083/500KV_Circuty_Breaker_XD.jpg

  17. Ch. 14. Dynamics and stability

  18. Smart grids, economics, optimization, etc.

  19. Tools we will learn to use PSS/E PowerWorld

  20. Groups • Some homework (particularly computer projects) will be assigned by group. • For group assignment please: • Rate your MATLAB familiarity (1-10) • Tell me the amount of real and reactive power consumed by a three-phase load, connected in Y to a 208V source, with a phase impedance of 10 Ohms, and a 0.866 lagging power factor. • Show your work!

  21. Circuit with lagging power factor

  22. Ch. 1. A coal power plant

  23. One-line diagram

  24. Deregulation
