EG2070 FACTS and HVDC in Electric Power Systems 7.5 credits

FACTS (Flexible AC Transmission System) and HVDC (High Voltage Direct Current) are controllable devices whose functions are to enhance the security, capacity and flexibility of power transmission systems. Application of these components in power systems implies an improvement of

• transient stability
• voltage stability
• damping of power oscillations
• optimal power flow

The course starts with a review of static and dynamic issues in power systems. As a technical solution to theses issues, FACTS and HVDC will be presented. It will be shown that FACTS and HVDC may be a technical solution to these issues. It will be discussed in the course how these components are designed and also what functions they have. Then, basic mathematical models and control strategies will be presented for these components to analyze the impact of theses components on power system stability.

To be able in a written report and orally to

• describe how FACTS and HVDC are designed,
• explain their functions and abilities,
• derive basic mathematical models for these components, and apply these models to load flow, modal analysis and transient stability analysis,
• present and apply different control strategies to these devices,
• present, describe and explain results of simulations about the impact of these devices on power system stability, and power oscillation damping
• critically analyze other related projects

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

• LAB1 - Laboratory Work, 1.5 credits, grading scale: P, F
• PROJ - Project, 6.0 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 examination consists of a project work (home exam) and is divided into three parts: written report, oral presentation and acting as an opponent to assess one of the other project works. Furthermore, there is some compulsory progress activities, where the student will show his/her progress in the project work.

Project (home exam), 6 (hp).
Two laboratory exercises (incl. compulsory preparatory work), 1.5 (hp).
