## Intended learning outcomes

Upon completion of the course the student should be able to

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

The course is given in English, and treats models and

computation methods for power system stability and

control. In the course assignments these models and

methods are applied to solve realistic problems with

computer programs written in MATLAB.

The following areas are treated in the course:

• Stability: voltage stability, transient and smallsignal

stability, and simulation models.

• Control: power oscillation damping and frequency

control.

## Disposition

Lectures, assignments, exam and project.

## Eligibility

The course is intended for Ph.D. students in electric power

systems, but can also be interesting for students from other

fields of electrical engineering.

## Recommended prerequisites

Three-phase system, load flow calculations, per unit system and basic control theory
