Course information

Content and learning outcomes

Course contents *

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

Intended learning outcomes *

After passing the course, the student should be able to

  • create mathematical models for describing the dynamics of the power system
  • based on the derived mathematical models, apply different basic methods to
    a)    study and analyse the basic concept for the presented instabilities in power systems
    b)    improve the stability of the system based on basic control algorithms,
  • carry out the other intended learning outcomes by using Matlab numerically and present and discuss received numerical results.

Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale *

A, B, C, D, E, FX, F

Examination *

  • PROA - Project, 3.5 credits, Grading scale: P, F
  • TENA - Written examination, 4.0 credits, Grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

The final mark is equally to the grade on TENA.
