Course offering missing for current semester as well as for previous and coming semesters

## Content and learning outcomes

### Course contents

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:

Optimal load flow and sensitivity analysis: reactive power dispatching to decrease power losses.

Fault analysis: system models, and calculation of fault currents where there is an unbalanced fault.

Stability: transient and small-signal stability, and simulation models.

Control: power oscillation damping and frequency control.

### Intended learning outcomes

Upon completion of the course the

student will be able to

• Perform an optimal power flow for reactive power dispatching to decrease power losses.
• Analyze the system performance where there is an unbalanced fault, and also calculate the corresponding fault current.
• Create mathematical models for dynamic and stability analysis of multi-machine power systems.
• Describe and analyze electromechanical modes in power systems.
• Design excitation systems to improve transient stability, and power oscillations damping.
• Explain and perform frequency control.
• Apply the theory to real-life problems.

## Examination and completion

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

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

### Examination

• TEN1 - Examination, 7,5 hp, betygsskala: 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.

### Other requirements for final grade

One written examination, 7,5 (HEC).

### Opportunity to complete the requirements via supplementary examination

No information inserted

### Opportunity to raise an approved grade via renewed examination

No information inserted

### Ethical approach

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
