Denmark is increasingly moving forwards generating electricity from Renewable Energy Sources (RES). These plants are predominantly connected to the power system via power electronics interfaced devices (PEIDs). In 2030, RES will have the potential to supply all the power system’s demand, where additional 25GW of new RES capacity is expected to be installed compared with current supply by solar and wind.

The large integration of RES will result in significant changes to the Danish power system. The replacement of synchronous generators with PEIDs will have a negative influence on maintaining system frequency and system voltage if not properly handled. It will affect fault current level, the ability to maintain power quality and to prevent adverse control interactions. These critical capabilities must continue to be adequately handled even when operating close to 100% penetration of PEIDs, in order to continue to ensure stable power system. However, the existing screening metrics to assess power system stability, such as short circuit ratio and its extended indices, are not sufficient for stability screening of high-penetration power electronics interfaced systems. It is therefore important to develop accurate stability index and criteria through which stability of the entire power systems can be evaluated in an accurate and strategic manner for a 100 % power electronics interfaced system.

At the Department Power System Design, Energinet, an industrial PhD position in Development of Stability Screening Methodology for a 100 % Power Electronics Interfaced System in Danish Grid is available. This PhD project will focus on developing analytical methodologies for screening power system stability for grid planning purposes, which provide inputs and insights to workflow and strategies for system-level dynamics studies. The candidate will be employed by Energinet and enrolled as a PhD student at the Doctoral School of Engineering and Science, Aalborg University. Both university and company supervisors will be arranged to the PhD candidate.

University supervisor / co-supervisor: Claus Leth Bak / Frede Blaabjerg / Filipe Miguel Faria da Silva

Company supervisor / co-supervisor: Yicheng Liao / Jun Bum Kwon

What we offer
As an industrial PhD candidate, you will work part time at Energinet in Fredericia and part time at AAU Energy in Aalborg. There is the possibility of flexible periods in the company and the university, which fit your research. There is also opportunity for several-month research abroad at another institute.

At the Department Power System Design, Energinet, you will contribute directly to the Danish green transition, by dealing with real-life challenges, working with specialized power system stability experts, and playing an important role in developing future solutions for assessment of power system stability. You can learn more about Energinet at

At AAU Energy, Aalborg University, you will be educated with problem-based learning, work under a dynamic and international research environment, get access to extensive and leading workshop and laboratory facilities. You can learn more about AAU Energy at

Qualification requirements
Applicants to the PhD position must hold a degree equivalent to a Danish Master's degree. The applicant is expected to have the following merits.

  • Education background in electrical engineering and research experience preferrable in both power systems and power electronics
  • Ability to work with advanced theory and are equipped with strong analytical skills
  • Communication skill in English at a professional level. Speaking Danish would be an advantage.
  • Software skills, e.g., DIgSILENT PowerFactory, PSCAD, MATLAB/Simulink, and programming skills, e.g. Python
  • Flexibility and mobility to work both in Aalborg and Fredericia
  • Flexibility and ability to work in a team environment

Application and Contact
Send your application via the link. The application must include:

  • A motivated text wherein the reasons for applying, qualifications in relation to the position, and intentions and visions for the research topic (e.g., a brief project description) are stated.
  • A current curriculum vitae.
  • Copies of relevant diplomas and transcripts from previous university studies (undergraduate and master or its equivalent). The copies of originals shall be certified. If the originals are neither in English nor Danish, official English translations are requested.
  • Scientific qualifications. You may attach previous publications related the topic if there are any.
  • Additional qualifications in relation to the position, e.g., English test certificates, references/recommendations, etc.

The application deadline is 4 January 2023. We plan interviews 11-12 January (1st interview online) and 24 January (2nd interview in Fredericia). If you have any questions about the PhD position, you are welcome to contact Head of Grid Analysis Department, Christian Flytkjær, on telephone 0045 30 67 46 88 or Yicheng Liao, on telephone 0045 50105822.
