Intended learning outcomes

In order to pass the course, you need to show both orally and in written reports that you are able to

  • explain the various power system instabilities and dynamics in power systems,
  • explain and apply different methods for analyzing power system stability,
  • create mathematical models for dynamic and stability analysis of power systems,
  • demonstrate how the transient stability of a power system can be analyzed by using Equal Area Criterion,
  • analyze electromechanical modes in power systems, and design excitation systems to improve transient stability, and power oscillations damping,
  • perform frequency control,
  • reflect on, evaluate, and critically assess others’ scientific results.

Course main content

This course deals with power system stability and control. The course starts with a review of large power outages in the world. Then, different power system instabilities will be presented and discussed in the course. After that, we will be able to analyze the large power outages in the world presented in the first lecture. Also, different control algorithms for improving power system stability will be presented.


The course includes lectures, project work hours, and examination.
