Reliability of Power Electronic based Power Systems (PEPS) (2025)

Welcome to Reliability of Power Electronic based Power Systems (PEPS) (2025)

Description: 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.

Key words: Reliability of power electronics, stress-strength analysis, design for reliability, wear-out failure, Ansys, Number of cycles to failure, maintenance

Prerequisites: The participant must have knowledge and competences like the level of an engineer with a MSc in power electronics, probability and control of power electronics converters. The relevant topics of reliability will be provided as pre-read documents and will be covered during teaching. 

Learning objectives: 

1. Fundamental concepts of reliability Engineering
2. Structural reliability and stress strength analysis
3. Introduction to converter reliability prediction
4. Impacts of converter control on PEPS reliability
5. Reliability modeling in PEPS
6. Model-based design for reliability in PEPS
7. Model-based maintenance scheduling in PPES
8. Reliability enhancement in PEPS
9.  Challenges and opportunities

Teaching methods: Lectures, Group work, Presentations, Small assignments, Excercise

Form of evaluation: Active engagement during the course and report on the two mini projects. 

Criteria for assessment: Active engagement during the course and report on the mini projects. 

Remarks: In total about 56 hours (26 hours teaching and practicing, 10 hours for preparations, 20 hours for finalizing a student report and XX (TBA) hours for examination)
