The overall goal of this course is to provide a basic knowledge of reliability theories with applications for the electric power system and its components. The course provides a basic introduction to reliability theory and general methods. Then the course sheds light on various issues for electric power systems which can be studied with reliability analysis, and shows examples of solution methods. Furthermore, the course includes an introduction to general methods for maintenance management, including methods for life cycle cost analysis, including assessment of environmental impact. One of the key features of the power system is the constant requirement on balance between generation and usage of electricity (typically expressed as load). In all these different steps there are different unknown features with stochastically behaviour, and obviously one main concern is the prediction of forecast for generation and load. Today´s development of the electric power system has a main driver being a facilitator for the sustainable energy system targeting different political targets. A sustainable energy system involves key components of; increasing use of renewable energy resources, increased energy efficiency and use of electricity in the transportation sector. As an effect of this some key questions for the electric power system are; integration of intermittent electricity generation e.g. from wind power, and connections of electrical vehicles to the electrical distribution system and different solutions for energy storage. The concept of Smart Grid captures these developments, which put new demands, challenges and possibilities for the electric power system. The electric power system is a complex technical system. The Smart Grid deployments add to the complexity including an energy system perspective, and new features for increased flexibility, and with same requirements on reliability in electricity supply.
The next course opportunity will be in 2021 starting on June 7.
The course is divided into the following parts:
This course will give a thoroughly introduction of fundamental reliability theory and basic models for analysis. The theories are generic and applicable for any technical system. This course is focused on application for electric power systems and its equipment in the context of being an enabler for the future sustainable society. Moreover the course includes introduction to methods and concepts related to: asset management, predictive maintenance methods, life cycle cost analysis and circular economics. Examples will be given from practical and own research studies. The application examples include: generation (hydro, nuclear and wind, solar), transmission and distribution and main components (cables, lines, circuit breakers, transformers) and usage and storage (meters, electrical vehicles, battery storage). The overall objectives of the course are that the participants after completed course shall be able to use: reliability assessment and asset management methods as major tools for decision support for design, operation, maintenance and planning of electric power systems.
After completing the course, the participant should be able to:
Entry requirements for this course is equivalent to master exam in Electrical Engineering, or corresponding and with basic knowledge in statistics methods.

If the course is discontinued, students may request to be examined during the following two academic years.
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
