Course Goals: The goals of this course are to enable you to
1. Freely use the language of power system dynamics;
2. Relate analytical models to power system dynamic behavior;
3. Perform dynamic analysis of electric power systems using commercial grade simulation software;
4. Assess the reasonableness of observed power system dynamic behavior.
Grading: exam 1 (20%), exam 2 (20%), final exam (20%), project report (20%), HW (20%).
Assignments: There are 4 different types of activities in which you will be involved.
1. HW: There will be daily readings and also problem sets. You are expected to do all reading and all problem sets..
2. Exams: The exams may be take-home or in-class but will be announced.
3. Final exam: The final exam will be a 2 hour written exam with cumulative coverage.
4. Project: Each student is required to complete a special project. Requirements for this will be defined later.
All assignments can be submitted by fax at 515-294-4263 or by e-mail.
Textbook: "Power system control and stability," by P. Anderson and A. Fouad, revised edition, 2003, Wiley amd IEEE Press.
Note that the text has appeared in 3 different editions: 1977, 1994, and 2003. The 1977 edition has quite a few typos in it so I would
not recommend using it. If you already have the 1994 edition, that will be fine for this course, but you should realize that the 2003 edition
has additional material contained in 4 extra chapters on mechanical torque and prime movers. This additional material will be covered in an
advanced course in power system dynamics to be taught Fall, 2003 (together with excitation systems).
