CANCELLED - Introduction to Stability of Electric Power Systems (2023)

Description: The course will provide training and education in the field of stability theory, stability of modern electric power systems with synchronous generators, power electronics-interfaced renewable generators, and other power electronic systems, such as HVDC and Flexible ac transmission systems (FACTs).

The PhD course will cover basic knowledge of stability theory, electrical power system stability, impacts of power electronic conversion system, electrical machines and renewable energy generators on the system stability, especially, the stability under the large scale integration of renewable generators and significant reduction of conventional synchronous generators.

Some of the course contents are based on recently obtained research results

The main topics are as follows:

·       Overview of power system stability and classification

·       Basics of stability theory

·       Angle stability

·       Frequency stability of power systems

·       Voltage  stability of power systems

·       Multi-time scale and quasi steady state simulation

·       Frequency response and regulation of renewable energy plants

·       Small signal stability and analysis method

·       Large signal stability and analysis method

·       Sub-synchronous oscillation

·       Stability of power electronic dominated power systems

Important information concerning PhD courses:


We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce 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 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. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
