Introduction to Stability of Electric Power Systems (2026)

This course introduces PhD students to the theory and analysis of electric power system stability, with a focus on the emerging challenges in modern, converter-dominated power systems. As renewable energy sources and power electronics replace conventional synchronous machines, new forms of instability are arising. The course provides foundational knowledge in power system stability and modern perspectives, including small and large signal stability, sub-synchronous oscillations, and inverter-driven dynamics. The motivation stems from the need to understand how large-scale integration of renewable energy affects dynamic behavior and system stability. Selected topics reflect recent research and practical challenges in grid stability analysis and control.

Including learning objectives: By the end of the course, participants should be able to:

• Understand the classification and theory of power system stability
• Analyze frequency, angle, and voltage stability phenomena
• Distinguish between small-signal and large-signal stability methods
• Explain the influence of power electronic converters and inverter-based resources on system dynamics
• Apply simulation tools to assess and improve system stability

Prerequisites: 

Participants should preferably have general knowledge of electrical engineering, including familiarity with dynamic systems, control theory, and basic power system concepts.

Important information concerning PhD courses: 

There is a no-show fee of DKK 3,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before the start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start of the course.

We cannot ensure any seats before the deadline for enrolment, all participants will be informed after the deadline, approximately 3 weeks before the start of the course.

For inquiries regarding registration, cancellation or waiting list, please contact the PhD administration at phdcourses@adm.aau.dk When contacting us please state the course title and course period. Thank you.
