Power System Dynamics, Winter 2025
Class Syllabus
We will cover how to think about power system dynamics, from various models to current challenges. It is surprising nontrivial to understand why the power system is stable, since disturbances occur constantly–from turning on and off lights to lightning strike on the lines–and there is no explicit real-time communication in the grid. We will develop a rigorous way of looking at system dynamics and explain what measures are taken and what control schemes are implemented to maintain the stability of power systems. We will get to a point where we can read and understand advanced methods as described in recent papers published in the scientific literature. For more information, see syllabus.

Class: WF, 12:30-2pm, ECE 026 .
Instructor: Baosen Zhang, zhangbao@uw.edu, Office: ECE M310
Office Hours:
- My office hours: Thursdays at 2pm.
- You’re welcome to schedule other times by emailing me.
Note:
- I will try to respond to emails within 24 hours. Please write EE552 in the subject.
- ou will need to do computer simulations for some homework problems. You may use whatever language you are comfortable with, e.g. Matlab, Python, R, C++, Julia,… As long as you can do the homework questions.
References:
There are no required textbooks for this class. Some references that maybe helpful are:
- '’Power System Dynamics – Stability and Control’’, J Machowski, Z Lubosny, J W Bialek, J R Bumby, Third Edition, Wiley 2020 (A standard textbook)
- '’Power System Stability and Control’’, Prabha Kundur, McGraw Hill, 1994 (The classical book on this subject, although it can be intimadating)
- '’Power System Dynamics and Stability’’, Peter W Sauer and M A Pai, Prentice Hall, 1998 (A more mathematical treatment of the subject)
- '’Voltage Stability of Electric Power Systems’’, T Van Cutsem, C Vournas,, Kluwer, 1998 (A detailed book on voltage stability)
Schedule of Classes:
- Introduction to power systems operations and stability
- Components of the power system, frequency and voltage stability
- Linear systems
- Power system small signal stability
- Lyapunov stability
- Lyapunov stability, power system models
- Voltage stability
- Optimal control
- Power electronic control
Structure:
- Power system dynamics is complex and involves both mathematical derivations and intuitive arguments and is thus not easily understood. More importantly, because of the integration of renewables, many ideas and techniques are changing in real-time. Just listening to a lecture is not going to be that useful. Instead, we will take an active approach to learning.
- There will be biweekly homework assignments.
- Some homework questions will be hard, and you’re not expected to have solved it completely. You will be graded on whether you have made a solid attempt at solving the problem.
Grade Distribution:
Homework 80% and participation 20%
Homework Assignments:
- Homework 1, due Jan 21st, 11:59pm. Submit to CANVAS.
AI Policy:
AI content generators, such as ChatGPT, present opportunities that can contribute to your learning and academic work. If you use such tools, you must clearly state where they are used and how they contributed to your work. Otherwise, using these technologies may violate academic standards of the University.
