PhD Stipend in Modeling and harmonic mitigation in large scale power electronics based power system (14-14065)

At the Faculty of Engineering and Science, Department of Energy Technology a PhD stipend is available within the study programme Energy Technology. The stipend is open for appointment from January 1, 2015. 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 200 employees – of which around 100 are PhD students. The laboratory-facilities are of world-class standard and the research is generally carried out in collaboration with the industry.   

Job description

Objectives: To be able to define and perform stability of a given larger power electronic based system which might include calculation of the overall risk of harmonic resonance problems as well as system resonances. Solutions to solve the problems are also of importance.

Research content: A complete model of a defined power electronic based power system (eg. on-shore or off-shore wind farm, PV power plant, HVDC-based system) needs to be developed in order to be able to test the developed component models, the power electronic interfaced generators/loads and their control which so far are developed in the project Harmony. Further the models should be able to identify and demonstrate harmonic problems, harmonic identification algorithms and also test new concepts for harmonic mitigation. As bus structure one of the IEEE standard buses will be used and scaled according to a specific location. Parts of the system operation needs to be demonstrated and also validated by experiments.

The stipend is affiliated with the ERC Advanced Grant “Harmony” which is hosted by Aalborg University and with Professor Frede Blaabjerg as Advanced Grant holder and started in 2012. The project is carried out in close collaboration with international universities as well as companies now are joining the activities. The overall mission in Harmony is to investigate whether it is possible to establish a reliable power system which has a dominant amount of power electronics based sources and loads by means of analysis tools and control? It is a 5 year program with around 10 researchers involved.

Applicants for the PhD position should hold a Master’s Degree in Electrical Engineering with a solid background in power system, control and power electronics systems. Theoretical skills combined with experience with experimental work will give a clear advantage with respect to other candidates as well as the ability to publish in high level journals. Good skills in oral and written English are also required.

The applicant must provide and upload a proper project description, which describes the applicants 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. The project description should have a length of 4-5 pages. 

You may obtain further information from Professor Frede Blaabjerg (flb<στο>et.aau.dk) concerning the scientific aspects of the PhD stipend. Details about Harmony can be found atwww.harmony.et.aau.dk 

PhD stipends are allocated to individuals who hold a Masters degree. PhD stipends are normally for a period of 3 years. It is a prerequisite for allocation of the stipend that the candidate will be enrolled as a PhD student at the Doctoral School of the Faculty of Engineering and Science, in accordance with the regulations of Ministerial Order No. 1039 of August 27, 2013 on the PhD Programme at the Universities and Certain Higher Artistic Educational Institutions. According to the Ministerial Order, the progress of the PhD student shall be assessed every six months. It is a prerequisite for continuation of salary payment that the previous progress is approved at the time of the evaluation. 

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.
