Reliability of Power Electronics Based Power Systems


Content, progress and pedagogy of the module

The module is based on knowledge achieved during BSc programme on the power system operation and control, power electronics and basic probability theory.

Modern power electric based power systems (PEPS) are facing new challenges in terms of reliable planning and operation due to proliferation of power electronic converters. The course is aimed at providing an in-depth introduction to the reliability modeling, assessment and enhancement approaches in PEPS. The basic principles of reliability evaluation along with their application, current practices and solution methods in PEPS will be discussed.

Type of instruction

The Master's programme is based on a combination of academic, problem oriented and interdisciplinary approaches and organised based on the following types of instruction that combine skills and reflection:

  • Lectures
  • Class teaching
  • Project work
  • Exercises (individually and in groups)
  • Digital learning in different ways including flipped class room, blended learning, game or quiz
  • Supervisor feedback
  • Professional reflection
  • Portfolio work


Extent and expected workload

Since it is a 5 ECTS course module, the work load is expected to be 150 hours for the student.
