The Norwegian University of Science and Technology (NTNU) creates knowledge for a better world and solutions that can change everyday life.
Post Doctor position in Medium Voltage DC grid design and optimization for underwater applications (IE-149-2018)
The Faculty of Information Technology and Electrical Engineering, http://www.ntnu.edu/ie at the Norwegian University of Science and Technology (NTNU) has a vacancy for a 100% position (2 years) as a Post Doc researcher at the Department of Electric Power Engineering http://www.ntnu.edu/elkraft. The described Post Doc position is part of a research project on "High-Efficiency all-electric DC supply systems for subsea work-class remotely operated vehicles (HEROVs)". HEROVs is a joint research collaboration between NTNU and two industrial partners: Ingeteam Power Technology S.A. based in Bilbao, Spain, and Argus Remote Systems A.S. based in Bergen, Norway.
Information about the department of Electrical Power Engineering
Currently there are 12 Professors, 7 Associate Professors and 4 Lecturers at the Department of Electric Power Engineering. In addition, there are 4 Adjunct Professors, 2 Adjunct Associate Professors, 9 Postdoctoral researchers, 2 Researchers, about 35 PhD students, and 15 technical/administrative staff. Research activities are organized under two research groups: Power Systems Group and Power Technology Group. The department has a good laboratory infrastructure for research and education, as well as a mechanical workshop, supported by a technical staff of 10 persons.
The department has a wide range of teaching responsibilities, ranging from fundamental education in electric power engineering for other engineering students, Master’s programs in Energy and Environment, International MSc programs within Electric Power Engineering and Wind Energy, as well as PhD education and continuing education.
The increasing growth of offshore and subsea activities in deep and ultra-deep waters, underpinned by the steep increase in offshore wind farms deployments, oil and gas processes progressively moved to the seafloor and other niche applications such as deep sea mining, military and forensics, require high number of underwater vehicles. They have high power demands and must be capable of operating under extreme conditions. The focus of the HEROVs project is on work-class Remotely Operated Vehicles (WROVs), which have power ratings exceeding 200 kVA and operate in ultra-deep waters. The WROV industry is presently transitioning to all-electric solutions enabling higher reliability, reduced weight and improved efficiency and controllability, but this poses challenging requirements to their subsea power supply system.
The goal of the overall project is to design, analyze and experimentally verify high-efficiency all-electric DC power distribution systems for deep underwater vehicles based on medium-voltage DC (MVDC) technology. In particular, within HEROVs, a post doc researcher will investigate the design and optimization of the MVDC distribution grid, while a closely related PhD project will focus on the design and optimization of power electronic converters employed on WROVs.
Within this context, there is one vacant Post Doctor position available at NTNU within the field of "Medium Voltage DC grid design and optimization for underwater applications".
The successful Post Doc candidate is expected to identify optimal configurations for the DC power distribution grid used to supply power to different types of submerged loads by applying multi-objective optimization techniques. This shall result in the development of a tool to identify the best configuration from multiple standpoints (e.g. in terms of losses, weight, cost, etc.) and given operating conditions. The design criteria should take into account the technical choices made for the surface generator (e.g. converter design), as well as the load mission profile. Hence, the Post Doc candidate will need to work in close synergy with a PhD candidate and other researchers contributing to the project. The final result will be the small-scale laboratory testing of the selected grid system using Power Hardware-in-the-Loop techniques, in collaboration with the industrial partner, Ingeteam.
Applicants must hold a PhD degree within electrical engineering and experience with MVDC application and/or a good understanding of multi-objective optimization techniques applied to electrical grids. A strong background in stability and control of power electronic systems will be merited and experience with Hardware-in-the-Loop testing will be an advantage.
Excellent analytical and communication skills are required.
The candidates must have excellent collaboration skills as well as an ability to work independently.
The Post Doc position is expected to start in autumn 2018.
Applicants currently enrolled in a PhD programme who expect to pursue the PhD degree before the date of appointment must forward documentation for the date of their final exam.
For further information about position, please contact Professor Elisabetta Tedeschi by e-mail: firstname.lastname@example.org
Applicants are required to submit a one-page research proposal within the proposed research area.
