During the specialisation in Wind Power Systems, you will study the electrical aspects of wind power systems and learn about generators, power electronics, control techniques, power systems and integration of wind turbines in the electric power supply network.
You will explore questions such as:
- How do we ensure electric network stability when a large wind turbine is connected to the electrical system?
- Should direct current (DC) or alternating current (AC) transmission be applied to offshore wind farms of the future?
- What type of generator provides the highest efficiency in a given application?
- How can a wind turbine be protected against lightning?
- How do you design a micro electricity supply network comprising a wind turbine, energy storage and loads?
The teaching combines lectures, laboratory work and project work. In each semester (except for the last) you will spend half of your study time on courses and course work while the other half of your time will be spent doing a semester project. Each semester has an overall theme, and within this theme you conduct a semester project with your project group where you investigate and attempt to solve a relevant issue within your field of study.
The study programmes at AAU are based on problem based learning and project work, which gives you a unique opportunity to acquire new knowledge and competences at a high academic level in an independent manner. You get to apply theory to practice in your semester projects, which will better prepare you for your future career.
At the Department of Energy Technology, you will find well-equipped, modern test laboratories that enable you to conduct exciting laboratory experiments. These tests will verify the theoretical analysis that you apply during the project work.
The laboratories with advanced computer based measurement and control facilities allow you to perform realistic tests in the electrical and mechanical wind turbine area with possibilities for e.g. doing power system stability analysis and making power electronics converters.
Read more about the laboratory facilities.
This semester is common to the three electrical specialisations of the Master' programme in Energy Engineering: Electrical Power Systems and High Voltage Engineering (EPSH), Power Electronics and Drives (PED) and Wind Power Systems (WPS).
For students with a Bachelor of Science (BSc) degree from Aalborg University, the project work is 15 ECTS credits, whereas it is 10 ECTS credits (INTRO project) for students with a BSc degree from another university. The projects' technical topic is the same, but the students from another university have one extra course about Problem Based Learning (PBL) which is the primary teaching method used at Aalborg University.
The documentation of the project work is also different:
Students with a BSc degree from Aalborg University should:
- Document the project work with a paper, a poster and a presentation at an internal conference (CES) accompanied by an appendix report, all in English.
Students with a BSc degree from another university should:
- Document the work with a project report written in English.

1ST SEMESTER PROJECT FOR STUDENTS WITH A BSC DEGREE FROM AALBORG UNIVERSITY
You and your project group will analyse the dynamics of an electrical energy system or electrical apparatus. Your focus can be for example on electrical power systems, electrical drive systems, wind power systems or a combination of these. In such systems, short circuits, starting procedures, control issues, etc., demand that the dynamic performance of the systems must be studied. You analyse and model the system you have chosen, and then you do experiments in the laboratories to verify the physical system, a simulated model of the system, or parts of the system.
1ST SEMESTER INTRO PROJECT FOR STUDENTS WITH A BSC DEGREE FroM ANOTHER UNIVERSITY
During this semester, you will learn about the Problem Based Learning (PBL) method applied at Aalborg University by doing project work and writing a project report about an issue or a problem in relation to electrical energy engineering.

- Use of the induction machine as drive on an electric vehicle
- Non-linear model of 3-phase distribution transformer
- Model of grid connected wind turbine generator
- Voltage Unbalance caused by Electrification of the Danish Railway
- Impedance measurement of submarine cables

In the second semester, you and your project group will work with a wind turbine system that has to be controlled under time varying loads, either as a stand-alone system or coupled to a power network. You model, simulate and evaluate the system considering power quality and system stability. It must be determined whether any power compensation units/systems are necessary.
- Advanced Course in Electrical Power Systems (5 ECTS)
- Advanced Power Electronics and Applications (5 ECTS)
- Optimisation Theory and Reliability (5 ECTS)
- Interaction between Wind Power Generation Units and Electrical Loads or Power System (15 ECTS)
examples of pROJEcT topics
- Grid connection of large off-shore wind turbine parks
- Operation of wind turbines in isolated power systems
- Power quality of grid connected wind turbines.
During the third semester, you have different options to earn the required 30 ECTS credits:
- You can do an internship in Denmark or abroad, where you take part in the day-to-day operations in the business. During the internship, you will write a project about one or more of your tasks during the process
- You can do a semester at another educational institution abroad or in Denmark
- You can do a regular semester at AAU with courses and project work
- You can begin your Master’s thesis, so your work is spread out over both your 3rd and 4th semester.
Aalborg University has collaboration agreements with universities around the world, and the programme’s research environment has a wide range of internship contacts.
If you opt to stay at AAU, you will choose elective courses that give you 10 ECTS credits and you will work on a project that is based on a wind turbine system or a wind farm for which an optimisation, control or diagnostic system must be set up. You explore how the system may be improved in relation to power output, energy efficiency, lifetime extraction, fault detections, etc., and you test your ideas in the laboratories.
To practice scientific communication skills, the project’s result, or parts of it, must be published in an article written in English. This article is presented at an internal seminar (CES).
