Reliability Assesment in Electric Power Systems (2025)
Doctoral School of Engineering and Science at Aalborg University
Welcome to Reliability Assesment in Electric Power Systems (2025)
Description: The course on Reliability in Electric Power Systems focuses on ensuring a stable and continuous supply of electricity in increasingly complex power systems. As we integrate more renewable energy sources and advanced technologies, maintaining system reliability becomes essential. This course covers the basics of reliability, the impact of different system components, and the latest methods for assessing and improving reliability. Participants will gain practical skills to handle real-world challenges, ensuring power systems run smoothly and meet regulatory standards.
Key words: Markov Process, Availability, Capacity Outage Probability Table (COPT), Loss of Load Expectation (LOLE), Excepted Power not Supplied (EENS), System Average Interruption Frequency Index (SAIFI)
Prerequisites:
In a course on reliability in electric power systems, probability and statistics are crucial for analyzing the power system behavior. Although these concepts will be covered during the course, it is helpful to have a basic understanding beforehand.
This includes fundamental probability theory—such as sample spaces, events, and probability measures—as well as knowledge of random variables for modeling different events in power systems. Additionally, an initial review of common probability distributions (e.g., normal, exponential, binomial) and their applications will aid in understanding how to model system components and failures more effectively.
Learning objectives:
- Understanding the fundamental of system reliability engineering
- Understanding the concepts of power system reliability
- Exposure to probabilistic technique applications to power system problems
- Exposure to reliability cost/worth problem and investigating the tradeoff between reliability and economics
Teaching methods: Lectures, Group work, Small assignments, Excercise, Presentations
Form of evaluation: The course is evaluated by a report on two mini projects.
Criteria for assessment: Assessment is based on the combination of active engagement during the course and the project reports.
Remarks: In total about 95 hours (60 teaching and practicing, 15 hours for preparations, 20 for finalizing a student report)
