Textbook: "Power system control and stability," by P. Anderson and A. Fouad, second edition, 2003, Wiley and 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.

Course Prerequisite:  Familiarity with the following topics is essential: matrix algebra and calculus-based network analysis theory. Knowledge of electromechanical energy conversion (including basic electromagnetic field theory) at the level of the text by Fitzegerald, Kingsley, and Kusko is important. Such material is touched on at ISU in EE 303. Also, power system analysis methods at the level of one of the standard text books on this subject (Bergen & Vittal, Grainger & Stevenson, Glover & Sarma, Gross, del Torro, Saadat, and Elgerd) is important. Such material is taught at ISU in EE 456, EE 457.

Other Materials: Class notes and other materials (e.g., papers, etc) will be posted to the website.

Quizzes: There will be two 50 minute exams during the semester and a final exam. No make-up exams will be given, unless there is a legitimate reason for missing the exam that is not under the student’s control, and the student makes appropriate arrangement with the instructor in advance of the scheduled exam.

Assignments: Besides two semester exams and the final exam, there will be homework assignments.

HW: There will be daily readings and also problem sets. You are expected to do all reading and all problem sets.

Exams: The exams will be in-class; tentative dates are on the schedule.

Final exam: The final exam will be a 2 hour written exam with cumulative coverage.

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 to the instructor.

Class Attendance: You are strongly encouraged to attend class, but role will not be called. However, YOU ARE RESPONSIBLE FOR ALL INFORMATION PRESENTED IN-CLASS. The web site and instructor, although available to you, are not responsible for providing you with in-class information if you choose not to attend class.

Class Preparation: A schedule of topics is given under “schedule” of the web site. Although we may deviate from this schedule a little, if you are attending class regularly, you should still be able to use it to tell what reading you need to do before class.

Communication: Feel free to communicate with any of the instructors in any way that is convenient to you (after class, during office hours, phone, e-mail), for questions about the course material or assignments. E-mail is an especially good way, but response time here is variable, typically ranging from a minute to about 24 hours, depending on the nature of your questions and the instructors schedule.

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.

Disability Statement:

Please address any special needs or special accommodations with me at the beginning of the semester or as soon as you become aware. Those seeking accommodations based on disabilities should obtain a Student Academic Accommodation Request (SAAR) from the Disability Resources (DR) office. Any student who feels s/he may need an accommodation based on the impact of a disability should contact me privately to discuss your specific needs. Please contact the Disability Resources Office coordinate reasonable accommodations for students with documented disabilities. If you have a documented disability and anticipate needing accommodations in this course, please make arrangements to meet with me soon. Please request that a Disability Resources staff send a SAAR form verifying your disability and specifying the accommodations you will need. If you have a documented disability that requires assistance, you will need to go to the Disability Resource (DR) Office for coordination of your academic accommodations.
