About the position

The Faculty of Information Technology and Electrical Engineering (IE) at the Norwegian University of Science and Technology (NTNU) has a vacancy for a two year position as a Postdoc Research Fellow at the Department of Electric Power Engineering (IEL). The described Postdoc position is part of the research within the EU-funded project “Increasing the value of Hydropower through increased Flexibility - HydroFlex”.

About the Horizon2020 research project HydroFlex

The HydroFlex-project is a Research and Innovation action in Horizon2020 and has a total budget of about 6 M€ in 4 years. The research is conducted in collaboration with the HydroFlex-partners and the Norwegian Centre for Hydropower Technology (HydroCen). HydroFlex has 16 partners spread over 5 countries in Europe. The Postdoc fellow will work together with other researchers in the HydroFlex project and at the HydroCen research centre.

The research fellow will be a part of the Power Electronic Systems and Component research group

The position reports to the Head of Department, Prof. Ole-Morten Midtgård.

Duties of the position

Job description

A postdoctoral research fellowships is a qualification position in which the main objective is to qualify for work in academic positions.

The research fellow will be a full member of the scientific staff at the Department of Electric Power Engineering, and will, beside playing an active role in the further development of HydroCen research Centre, be expected to take part in activities such as teaching and relevant administrative tasks.

Project description

One of the main topics in HydroFlex is to increase the flexibility of hydropower. This is needed in order to meet the future demands in a world of unregulated renewables. Hydropower machines are traditionally operated at constant speed for power production and in pumped-storage mode. In order to enhance the flexibility of turbine and generator units, one solution is to introduce variable speed. This is partly applied today using Doubly-Fed induction machines. However, in this project the research fellow will work on control of a full power converter feeding a synchronous machine.

The research fellow will work on optimal control of synchronous machines and turbine units to improve efficiently and dynamic performance of the power station. It is further a goal to reduce the dynamic loading on waterways, turbines and generator by optimal control of the synchronous motor drive. This includes optimal modulation and control of multi-level converters. It is foreseen that the research fellow will do both theoretical research and implementation on a laboratory control platform.

Required selection criteria

Qualification requirements

The applicant must hold a PhD-degree in Electrical Power Engineering. The applicant must have research-based knowledge within at least in these areas:

  • Modelling of electrical machines and power electronic converters.
  • Digital control control of drives including experience in C++ and FPGA programming

The research fellow will be working in a group with other researchers and PhD candidates. It is expected that the selected candidate plays an active role in the development of further research activities in HydroFlex, supervise PhD candidates and lays a foundation for further research in the topic for this position.
