ENERGY ENGINEERING, MASTER

Academic content

Attending experiment


During the specialisation in Electrical Power Systems and High Voltage Engineering (EPSH), you will study future power supply sources and the structure of future power supply systems.

The programme combines power systems analysis with:

  • High voltage design
  • Network planning
  • Simulation models for analysis of steady-state, dynamic and transient phenomena
  • Compensation systems
  • Application of advanced control and surveillance strategies
  • Stability
  • Reliability
  • Voltage quality
  • Relay protection

You can explore questions such as:

  • Should the entire high voltage network be laid in cables? How should this be done?
  • How would the future distribution network be, including decentralised supply units? What control strategy would be required?
  • Should the customer pay time-dependent prices to encourage adjustment of consumption patterns?
  • Should the distribution network be able to run independently in the future (disconnected from the transmission network)?
  • How do we control the balance between production and consumption in a future network supplied by sustainable energy sources with fluctuating production and consumption?

The teaching in the programme takes place in an innovative, dynamic and challenging environment through a combination of research-based courses, team-based project work, and a high degree of interaction with industrial partners and energy supply companies.

The companies take an active part in providing project proposals for the problem-oriented project work, guest lectures and visits to the companies.

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.


ENERGY LABORATORIES

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 power system and high voltage engineering area, with possibilities for e.g. doing power system stability analysis and making power electronics converters and doing test in the smart grids and high voltage laboratories for instance.

Power system

1st SEMESTEr

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 small course about Problem Based Learning (PBL) which is the primary teaching method used at Aalborg University. Further, the students not having a bachelor degree from Aalborg University also has a course in Control theory and Matlab.

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

In the project, you and your project group will analyse the dynamics of an electrical energy system or electrical apparatus. Your focus can be for example 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 experiment in the laboratories to verify the system, a model of the system, or parts of the system.

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 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 system, a model of the system, or parts of the system.

1ST SEMESTER INTRO PROJECT FOR STUDENTS WITH A BSC DEGREE FORM ANOTHER UNIVERSITY

In 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.

You and your project group will analyse the dynamics of an electrical energy system or electrical apparatus. Your focus can be for example 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 system, a model of the system, or parts of the system.

Laboratory work

2nd SEMESTEr

In the second semester, the courses support your project work, which is based on the study of a component, an application or a process involving control or surveillance of electrical power systems (digital SRO-systems). You and your project group describe the system and make specifications for the control or supervision system. The system should be modelled and implemented in a simulation program. You simulate, analyse and evaluate different control and/or surveillance methods for the purpose of selecting a solution. The complete system (or parts thereof) or models can then be designed and implemented as a real-time system in the laboratory, or real-time data can be obtained from an existing system. You then test, verify and evaluate the implemented system and the control and/or surveillance strategies designed based on the set-up in the laboratory or real-life data.

3rd SEMESTEr

During the third semester, you have different options to earn the required 30 ECTS credits:

  • You can do a traineeship in Denmark or abroad, where you take part in the day-to-day operations in the business. During the traineeship, 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 elective 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 traineeship contacts.

Find out more about studying abroad and traineeship here.

Regular semester at AAU

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 an electrical power system or a high voltage system. You will set up and model an optimisation, control or diagnostic system, and the system must be implemented and verified experimentally 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).
