Stability in power grids, modelling and analysis

Modelling of a power system to simulate how it perform in different operation conditions and during faults/disturbances is important in order to assess the ability of the power system to operate securely, handle fault situations and changes in production and load. The course contains fundamental theory about stability in power systems. Different kinds of stability like voltage stability, transient stability, frequency stability and small signal stability are important themes in the course. The course contains modelling and methods to analyze the ability of power systems to sustain changes or disturbances. The course contains an introduction to modelling and simulation of power systems with digital tools in order to analyze power system stability.

Lectures, work with project/assignment, oral presentation, exercises.

Compulsory work requirements to get access to evaluation: Do an oral presentation with use of powerpoint (or similar) of a theme in stability in power grids or of an exercise. The presentation is delivered in the learning platform as a recorded video. The deadline for delivering the oral presentation will be given in the learning platform at the startup of the course.
