SEE030 Variation management in the electricity system VT23 (7,5hp)
Revised November 28th, 2022
Department of Space Earth and Environment
Course purpose
The aim of the course is to provide the student with knowledge of technologies and strategies to manage variations in the electricity system, with focus on variations in the time-span of hours to seasons. The course includes aspects of variation management on detailed technology and process level as well as a system level understanding of the role of different variation management strategies in electricity systems with large shares of wind and solar power.

Course literature
The literature consists of a combination of a compendium, book chapters and articles. The course compendium is available on the course homepage and include basic concepts adressed in the course. For book chapters and research articles, files and links are included in respective module. Literature under each module should be regarded as core course material unless marked as extended reading.
Course design
The course places emphasis on active learning. In learning activities, traditional lectures are combined with group work during which students answer questions on core content. The course also includes 5 mini-projects. In the mini-projects, the students apply knowledge gained in learning activities to large, open-end questions in small groups. Solutions are presented on mandatory presentation and workshop sessions. One mini-project per student is to be submitted as a written report. Two written exams are given in the course, one in the middle and one at the end, with focus on basic concepts and technical processes. For higher grades, a take-home exam, similar to the mini-projects, is given at the end of the course.
Videos and literature - the videos and literature introduce students to new knowledge based on recent research in the field. The content focus on the technical properties and cost structure of the different variation management strategies and how these decide the impact the strategies will have on the electricity system.
Learning activity - a typical learning activity starts with a short introduction to the topic and core concepts after which students answer questions on core content in groups and report on the board. The purpose of the group work is to enable students to anchor their knowledge of the content. The answers on the board are discussed in full class after which some recent research on the topic is presented. Students are encouraged to watch the video material in the related module before the learning activity.
Mini projects - the mini-projects are designed to practice applying knowledge gained from videos, literature and learning activities in this course and previous courses to open problem formulations. There are no “cook-book” examples and results will vary depending on choices and assumptions made. The purpose of this work is to reach a state of learning where knowledge can be deployed freely to the task at hand (accommodative learning in pedagogical literature). The process of reaching this level of learning is known to be frustrating but also rewarding since the knowledge acquired in this way is very accessible when needed to solve “real” problems at later stages in the career (master thesis, work etc.). Results of the work on the mini-projects is presented in small groups where we compare our findings and discuss different methods and assumptions. The discussion is intended to support the understanding of how methods and assumptions drive results and give feedback on problem solving strategies. More information on the mini-projects is found in Instructions to project sessions.pdf . Each mini-project is carried out in groups of 3. Results are presented and discussed in workshops of 8-12 students. The workshop sessions are compulsory.
Project report - each student write an individual project report on one of the mini-projects. The project report is evaluated and a pass is required to pass the course.
Duggas - duggas, or mid-term exams, take place the 13th of February and the 6th of March 2023. They address basic concepts taught in the course up until the exam. A pass on both exams is required to pass the course. Pass is the highest grade given.
Take-home exam - is made available on canvas on the 9th of March and is due the 17th of March. Similar to the mini-projects, the take-home exam requires students to apply their knowledge to a problem, design an own solution method and make assumptions and reflect on their impact on the result. The take-home exam corresponds to around two full days of work and is required to achieve higher grades.
Oral exam - students in between two grades or with very similar solutions on the take home exam will be called to oral examination.
Examination form
The examination is based on the written exams (pass/fail), active participation in the mini-project workshops (pass/fail) and one written mini-project report (pass/fail). Higher grades are awarded based on a written take-home exam. Passed mid-term exam and mini-projects are valid for one year.
Learning objectives
- Describe how variability impact the electricity system composition
- Explain how variations in load has formed the present electricity system
- Reflect on how variations in wind and solar power could influence the composition of the future electricity system
- Describe how the design of wind and solar power installations impact the variations in the electricity system in terms of technology choices, geographical distribution of power production and possibilities for power transfer.
- Apply classifications to explain similarities and differences between variation management strategies.
- Put forward the underlying technical processes behind variation management strategies.
- Discuss how the underlying technical processes impact the properties of the variation management strategies.
- Reflect on which actors are involved in different variation management strategies
- Evaluate different investment alternatives
- Discuss the benefits of different strategies from different actor perspectives
- Discuss the effects of up-scaling of variation management strategies on the environment and on resource availability.
- Discuss how the choice of variation management strategy depends on the electricity system context.
- Describe how variation management strategies impact the electricity system, in terms of marginal cost of electricity, full load hours of different generation technologies and investments in new power production.
- Reflect on how variation management strategies interact with each other.
