- Assignment 3
- Note that you should choose a time slot and a specific assignment from the doodle before you start working with the assignment.
- Each group chooses one of the Assignments 3a–3b from a "doodle" revealed in PingPong, under "Assignments", from 13:00, Friday, May 10. This choice also determines the time when your assignment is to be orally presented. All five occasions will include three presentations of each assignment 3a/3b—first come, first served! Your choice must be made at the latest on Monday, May 13 – after that, the doodle poll will be closed.
- Each group shall then present their assignment during ~12 minutes, including time for questions. A projector will be available for the presentations. If you need to borrow a laptop, you have to inform me at the latest on Friday, May 24, at 15:00.
- You will be asked to provide (written) feedback on each others oral presentations. This will be organized during the respective seminars.
- Note that presence is mandatory at one full seminar (i.e., approximately 90 minutes).
- The seminar hours are Monday, May 27, 10–12, 13–15, and 15–17, and Tuesday, May 28, 10–12 and 13–15.
- A detailed schedule for the oral presentations.
- A slightly updated version of the schedule.
- Another slightly updated version of the schedule (190527).
- Assignment 3a—Windpower investment and generation
- Assignment 3b—The Scandinavian electricity system
The course content is defined by the literature references (i), (ii), and (iii) in the course plan. The importance of each moment of the course is defined by the respective emphasis given by the lectures, exercises, and assignment tasks.
- In order to pass the course, the student should provide
(deadlines are indicated in the
in groups of (maximum) two persons:
- written reports of three assignments;
- an oral presentation of Assignment 3 (during week 22);
- a written opposition to Assignment 2;
- one report per assignment describing the distribution of the assignment work and the cooperation within the group;
- presence at at least one full seminar occasion (2·45 minutes; students' presentations of Assignment 3).
- in groups of (maximum) two persons:
- To be able to receive a grade higher than 3 or G, the written reports and opposition as well as the oral presentation must be of high quality. The individual reports, describing the distribution of the project work and the cooperation within the group, must also confirm the student's contribution to the quality of the reports.
- Students aiming at grade 4, 5, or VG must also pass an oral exam.
- The oral exam will cover the theoretical material, including problem solving, as defined in the course plan for the books by Lundgren et al. and Henningsson et al., and including the supplementary material on multiobjective optimization (from Rardin's book). The emphasis on each of the different subjects is mainly defined by the notes from the lecture series of the theoretical material and from the problem solving sessions.
The oral exam is organized as follows:
- The student receives 4–5 exercises and may study these for 1/2 hour in a separate room.
- The oral examination will then take place for 1/2 hour.
- No equipment except for pen, ruler, rubber, and paper are allowed during any part of the oral exam.
- The oral exams are given during the exam weeks, on a subset of the dates June 3–5 and 10–12. Each student eligible for the oral exam will receive an invitation to sign up for this.
The randomly selected course representatives are presented in PingPong.
Being a student representative means that you are responsible for evaluating the course together with the examiner/course responsible and the program board of the program that gives the course.
The evaluation process consists of three parts:
- The student representatives and the teacher are expected to have two informal meetings during the course. The first one should be in the first study week, the second one after approximately half the course. The first meeting is mostly for you to get acquainted, the second one are for the student representatives to give feedback to the teacher on the progress of the course.
- After the course an evaluation questionnaire is sent out. The examiner will get a chance to add extra questions to the standard questionnaire.
- After the course, there will be an evaluation meeting where the student representatives and the examiner/course responsible for the course have a meeting together with the program board of the program who gives the course, discussing the courses' advantages and potential for improvement. This meeting will be held in study week 3–6 in the study period after the examination. The examiner invites the participants to this meeting.
