Grading:          Homework 35%
                        Class participation 15%
                        Mid-term I 15%
                        Mid-term II 15%
                        Final Exam: 20%

Lectures will focus on presenting the context, motivation and intuition for the main concepts, but you will need to read the textbook and complete the homework assignments to develop your mathematical understanding and analytical expertise. You should expect to spend 6-9 hours per week on this class in addition to attending lectures.

Homework is due at the beginning of class on the specified due dates. Late homework will be accepted up to one week late, but with a 50% late penalty.

All exams are closed-book, closed-notes. You may bring in one page of notes (8.5" by 11", single-sided), and may use standard calculators.

# of hours (approx.)

Topic

2

Chapter 1: History and trends in the electric power system, introduction to PowerWorld software

4

Chapter 2: Fundamentals – phasors, instantaneous and complex power, network equations, balanced three-phase circuits

2

Chapter 3: Power Transformers – representation of ideal and practical transformers, per-unit system

8

Chapter 4: Transmission Line Parameters – resistance, stray conductance, inductance and capacitance (4.7, 4.11, and 4.12 can be skimmed)

4

Chapter 5: Transmission Line Operation – approximations, differential equations, equivalent π circuit, lossless lines, constraints, reactive compensation

8

Chapter 6: Power Flows – the power flow problem, solution methods, control of power flow, fast decoupled power flow, “DC” power flow

2

Chapter 10: System Protection – preventing damage and containing outages

6

Chapter 12: Power System Controls – maintaining balance between supply and demand, at the lowest cost

2

Wind & solar power – integrating intermittent power sources

(4)

Chapter 7: Symmetrical Faults – power system behavior during transients and short circuits (if time permits)

This course focuses on planning and operation of the power system to avoid failures. Students are advised to study chapters 7-9, 11 & 13 to learn about system behavior during faults, and chapter 14 to learn about the low-voltage distribution network (e.g., for integrating PV or EVs).
