The Department of Wind Energy in the Technical University of Denmark (DTU Wind Energy) is seeking a PhD for the Integration and Planning Section (INP).


DTU Wind Energy is a mission driven university department with a vision to be the preferred university partner for the global wind energy sector. The department creates value for society through integration of research with education, innovation and research-based consultancy within key fields central to the development and use of wind energy.


You will be part of the international team carrying out research in Integration and Planning Section where the working language is English.


Our research is function oriented in the sense that we direct the research towards issues that are relevant for industrial development and applications, and we work in projects with system integration, control concepts for wind turbines, wind power plants, electrical components, grid connection and large-scale wind energy penetration.


Please look at for more details on the type of activities we undertake.  


InnoDC is a European Training Network (ETN) funded by the European Union’s Horizon 2020 Marie Skłodowska-Curie Actions programme. ETNs provide training through doctoral research to talented early stage researchers (ESRs). Through 15 ESR research projects, InnoDC will address the technical challenges linked to the development of offshore grids and hybrid AC/DC systems.


This is a unique opportunity to study for a doctoral degree in a network of wind power and power systems experts from academia and industry. We are therefore looking for high qualified and motivated candidates with the skills, background knowledge and enthusiasm to help the network make important research breakthroughs.

  • The appointed researchers can be of any nationality and must have the necessary academic skills and background (electrical engineering, power systems, power electronics, renewable energy, optimization, control systems) to make the success of a doctoral degree.
  • Applicants are required to have completed Bachelor and Master studies before starting the work.
  • On the date they start work (aimed to be April 2020), researchers must not have lived in the country of the host organisation (see below) for more than 12 of the previous 36 months, must have less than four years’ full-time equivalent research experience and must not have a doctoral degree.
  • All researchers will participate in international secondments to other organisations in the InnoDC network and in outreach activities with audiences beyond the research community.
  • It is a requirement that network ESRs have an ability to understand and express themselves in both written and spoken English to a level that is sufficiently high for them to derive full benefit from the network training.
  • Female candidates are especially encouraged to apply as women are underrepresented in this field of research.

Responsibilities and tasks

The PhD project focuses on the development of suitable control strategies for clusters of offshore wind power plants (OWPP).

The main objective is to first analyse the challenges that can arise when several wind power plants, with wind turbines from different manufacturers, are connected to the same large HVDC converter. Secondly, the study will develop methods for implementing coordinated and synchronized active power control and reactive power management in the wind cluster.

The main research tasks:
  • Develop OWPP cluster model including generic representation of wind turbines
  • Implement and analyse cluster supervisory controller for coordinated and synchronized active power control
  • Implement and analyse cluster supervisory controller for reactive power management, both in normal and fault operation
  • Analyse and mitigate the converters control interactions in HVDC connected wind power plants  
  • Evaluation of stability and robustness of the chosen solutions

The PhD project is a collaboration with Vattenfall, through the InnoDC project.


Candidates should have a master's degree in engineering or a similar degree with an academic level equivalent to the master's degree in Electrical Engineering / Power Electronics / Power Engineering.


The successful candidate is required to have:

  • Documented background in converter modelling and control
  • Documented background in at least one power engineering simulation tool, e.g. PSCAD, PowerFactory, Simscape Power Systems
  • Knowledge on wind turbine / wind power plant technology
  • Ability to work in a project team and take responsibility for own research goals
  • Fluency in communicating and reporting in English
  • Prior experience with converter based experimental systems will be appreciated.

Approval and Enrolment

The scholarship for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.


The assessment of the applicants will be made by Prof. Nicolaos A. Cutululis, Assoc. Prof. Anca D. Hansen and Head of Section Jens Carsten Hansen
