Integrated PHD STIPEND in Multi-time scale modeling of power electronic converters in power system applications (14-17029)

At the Faculty of Engineering and Science, Department of Energy Technology an integrated PhD stipend is available within the general study program Energy Technology. The stipend is open for appointment from September 1, 2017. The Department of Energy Technology is an expanding department covering most fields of Energy Technology ranging from electrical energy (Power Systems, Power Electronics, Electrical Machines to thermal energy including Energy Systems and Fluid Mechanics and Combustion but also mechatronic systems. The department has about 250 employees – out of them are more than 100 Ph.D. students. The laboratory-facilities are world-class and the research carried out are most often in collaboration with the industry. The stipend is offered in relation to the research programme " Reliable and Efficient Power Electronics" and the PhD student will be positioned at the section for Power Electronic Systems.   

Job description

The PhD stipend is a part of a research grant on Reliable Power Electronic based Power System (REPEPS) from the Villum Foundation Investigator programme running from 2017 to 2023 which is awarded to Professor Frede Blaabjerg. The stipend is further related to the research programme Efficient and Reliable Power Electronics and the PhD student will be positioned to the section for Power Electronic Systems.

The overall goal is to develop new methods for ensuring reliable and safe operations of power electronic based power systems. An integrated reliability assessment tool, which can incorporate both the physical characteristics of hardware components and control software optimization at the system level, will be developed for predicting the lifetime of power electronic based power systems. New insights into the mutual interactions of power electronic converters at multiple time scales will be revealed to leverage the control effects of power electronics for power grid stabilization and protection. It is expected that between 15 to 25 researchers will be involved in REPEPS and the research environment will be very international oriented.

Combining reliability assessment of power electronic based power system with power system stability analysis involves modelling in multiple time-scales - both in terms of the loading of the analyzed individual components as well as the control dynamics looking at different time scales. This project should develop a modelling and analysis framework enabling a power electronic system reliability assessment with different grid dynamics and may involve the use of different analysis tools as well as being able to do model reductions combined with statistical analysis of modern power electronics based power system. Some of the outcome should also be validated by experiments.

Integrated PhD stipends are allocated to individuals who has not yet completed a Master’s degree and who wish to begin the PhD study in connection with the Master study. Thus a prerequisite for acceptance is that the candidate is enrolled in a relevant Master’s programme.

The stipend consists of two parts, A and B. During part A you are enrolled simultaneous in the Master’s programme and in the PhD programme. The stipend consists of two SU-PhD Grants per month (SU=The Danish students’ Grants and Loans Scheme). One SU-PhD grant equals DKK 5.903 (2015 level). SU-PhD Grants are paid for a maximum of two years. When the Master’s degree has been obtained, you will be employed for two years as a PhD fellow according to the present collective agreement. Part B has a maximum duration of two years.

Applicants should be highly motivated with a background in power electronics, modeling and control of electrical energy systems. Hardware experience with power electronics systems will be an advantage. A high proficiency in oral and written English is required.

The applications for enrolment must include the following:
•    Letter of motivation.
•    BSc diploma and grade transcripts from the Master's programme.
•    Curriculum vitae.
•    Publications (if applicable).
•    Project description (4-5 pages), which describes the applicant’s initial thoughts and ideas related to the specific project applied for. This includes a brief state-of-the-art (including short list of references), a time schedule and how the applicant intends to shed light on the project objectives.
•    A list of outstanding ECTS points in the Master's programme (can be attached in the boxes for references or publications).

You may obtain further information from Professor, Villum Investigator Frede Blaabjerg, Department of Energy Technology, phone: +45 21292454, email:, concerning the scientific aspects of the stipend.

The qualifications of the applicant will be assessed by an assessment committee. On the basis of the recommendation of the assessment committee, the Dean of the Faculty of Engineering and Science will make a decision for allocating the stipend.

For further information about stipends and salary as well as practical issues concerning the application procedure contact Ms. Helene Ulrich Pedersen, The Faculty of Engineering and Science, email:,  phone: +45 9940 9803.

The Faculty have a research school, The Doctoral School of Engineering and Science: and a Network for all PhD students:  

The application is only to be submitted online by using the "Apply online" button below.


Allocation of SU-PhD Grants are according to the Ministerial Order on the State Educational Grant and Loan Scheme part 12, section II. This applies only to integrated PhD stipends. Appointment and salary as a PhD fellow are according to the Ministry of Finance Circular of March 26, 2012 on the Collective Agreement for Academics in Denmark, Appendix 5, regarding PhD fellows, and with the Ministry of Finance current circular on the employment structure at Danish Universities.
