About the position

The Department of Electric Power Engineering, has one vacancy (100% positions) as PhD candidate within the area of: “Energy storage for grid services in HVDC connected offshore wind farms".

This PhD project is part of the newly established FME NorthWind (Norwegian Research Centre on Wind Energy) that has as aim to bring forward outstanding research and innovation to create jobs and grow exports, and to facilitate the sustainable development of wind power. The Centre is led by SINTEF, with research partners NTNU (Norwegian University of Science and Technology), UiO (University of Oslo), NINA (The Norwegian Institute for Nature Research), and NGI (Norwegian Geotechnical Institute). The Centre involves more than 40 national and international industrial partners that, together with the research partners, comprise a world leading consortium for the development of a sustainable wind energy future.

The prospective candidate will work in the research group Power Electronic Systems and Components (PESC).

The main supervisor of the PhD candidate will be Prof. Elisabetta Tedeschi.

The position reports to the Head of Department.

Duties of the position

With the European Union setting the ambitious goal of installing 60 GW of offshore wind power by 2030 and 300 GW by 2050, and many other countries embracing similar policies to decarbonizing electricity and supporting a more sustainable society, there is a significant need for technological advances and increased competitiveness to drive the growth of offshore renewable energy and electric infrastructure in the coming years.

Within this context, this PhD project will investigate different options for integrating energy storage into HVDC-connected offshore wind power plants, in order to provide grid ancillary services.

It will primarily investigate the possibilities to embed or exploit energy storage provided by the different converters in the offshore wind power plant, in relation to the type of grid service required. It will discuss the implications of different alternatives in terms of: 1) storage location (i.e. in the wind turbine, on the collection grid converter -if present-, at the interface with the onshore grid); 2) storage/converter sizing, depending on storage type; and 3) control implementation based on the grid support service to be provided.

The proposed solutions are expected to be validated in a laboratory environment through the Hardware-in-the-Loop approach, reaching the Technology Readiness Level (TRL) 4.

The PhD is foreseen to collaborate with national and international partners, among which SINTEF Energy Research and the Technical University of Denmark (DTU), which will contribute to the co-supervision of the PhD candidate.

The candidate must engage in the FME NortWind activities as required.

Required selection criteria

The objective of the PhD education is to qualify for scientific research of high international standard. The PhD education has a nominal duration of three years of full-time study and includes required coursework or similar academic training comprising a minimum of 30 credits. The most important component of the PhD education is an independent scientific research project carried out under academic supervision, which results in the PhD thesis. The PhD degree is conferred based on these two elements and the doctoral examination, which consists of a trial lecture and a public defence of the scientific thesis.

The candidate is expected to fully complete the course work and the PhD thesis within the period of employment, which could be 3 or 4 years. The doctoral examination may take place after the period of employment. The option of 4-year employment would imply 1 year of duties as teaching Assistant for the Department and may be offered to a candidate with clear motivation and ability for such work, if the Department sees the need. This will be clarified during and after any interview.

The qualification requirement is completion of a master’s degree with strong academic background with a grade of B or better in terms of NTNU’s grading scale.

Applicants for the PhD position must hold a M.Sc. degree (or equivalent) within electrical engineering and have a strong background in power electronics control, and good knowledge of basic concepts of power systems stability and operation. Competence on HVDC grid related technology and control, and experience with real-time simulations and Hardware-in-the-Loop testing (especially with OPAL-RT) will be an advantage.

Relevant scientific publications in international journals and peer-reviewed conferences are merited.

Applicants for the position are required to submit a one-page research proposal within the proposed research area.

The PhD project requires excellent analytical and communication skills.

The applicants for the position must be able to work independently, but also to collaborate with the other project participants and other colleagues at the department.

Other qualifications:

Applicants must have very good English language skills, written and spoken. Applicants from non-English speaking countries outside EU/EEA/Switzerland must provide preliminary documentation of English language proficiency, in terms of an approved test. The following tests can be used: TOEFL, IELTS and Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE).

Further assessment of both written and oral English language skills and the ability to communicate fluently will be conducted in the continued selection process and during any interviews for all applicants.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, post doctor and research assistant.

NTNU is committed to following evaluation criteria for research quality according to The San Francisco Declaration on Research Assessment - DORA.
