About the job
With the European Union setting the ambitious goal of reaching carbon neutrality by 2050, and many other countries embracing similar policies to decarbonize electricity, supporting a more sustainable society, there is a significant need for technological advances and increased competitiveness to drive the growth of offshore renewable energies, and energy storage in the coming years.
Within this context, this PhD project will focus specifically on investigating how to ensure that large amounts of offshore wind energy can be integrated into the electric grid without jeopardizing its stability due to resonance phenomena and harmonic interactions.
The PhD Candidate will be employed at Norwegian University of Science and Technology (NTNU) and the workplace will be in Trondheim, Norway, but the PhD-project is of both academic and industrial relevance, and it will therefore be developed in close cooperation between NTNU in Trondheim and the company Petronas, which is a global Malaysian energy group.
Your immediate leader is the Head of Department.
Duties of the position
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 defense of the scientific thesis.
In the scientific research project, the PhD candidate will investigate the risks in terms of harmonic resonances/harmonic instability which may arise from the increase in power level and distance from shore of wind turbines (as well as PV farms) with ac collection systems, and how they depend on the operating conditions of the farm.
Among the specific objectives of the PhD project there are:
- To identify a realistic use-case (baseline case) for a large offshore wind park (or possibly PV plant) with ac collection grid.
- To model the identified test case in MATLAB or DIgSILENT to replicate the problem, in such a way that it is possible to parameterize turbine type (Type 3 or Type 4) or PV, network with varying grid strength, short circuit ratio, etc.
- Validate various operating modes of the wind farm (e.g., constant PQ mode, voltage/frequency support mode or grid forming mode) against the baseline test case.
- Capture harmonic resonance and stability issues depending on number of wind turbines (or PV panels) in operation, wind speed (or solar irradiation), cable length, converter topology and control, etc. both theoretically and by simulations.
- Identify critical parameters for resonance/instability.
Required selection criteria
Applicants must hold an M.Sc. degree (or equivalent) within electrical engineering with a specialization or solid competence in dynamic modeling of electric power systems.
- Good knowledge of the basics of power electronics and power systems is needed.
- Your education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master’s level.
- You must have a strong academic background from your previous studies and an average grade from the master’s degree program, or equivalent education, which is equal to B or better compared with NTNU’s grading scale. If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education.
- Master’s students can apply, but the master’s degree must be obtained and documented by autumn 2023.
- You must meet the requirements for admission to the faculty’s doctoral program.
- Applicants must have good English language skills, written and spoken. Applicants from non-English speaking countries outside the 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). Minimum scores are:
- TOEFL: 600 (paper-based test), 92 (Internet-based test)
- IELTS: 6.5, with no section lower than 5.5 (only Academic IELTS test accepted)
- CAE/CPE: grade B or A
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 the shortlisted applicants.
The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Phd candidate, research assistant and specialist candidate and Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant
Preferred selection criteria
- Experience with offshore renewable energy systems will be an advantage.
- Communicates information with clarity and ease, both orally and in writing.
- Self-driven with a strong ability to work both independently, and in cooperation with others when required.
- Shares information and expertise to achieve the desired results.
- Structured, targeted and solution-oriented.
A good working environment is important to us at the Department of Electric Energy. Our working environment is characterized by an informal and friendly tone and good cooperation between employees. We therefore want you to be a person who
- works from campus and participates in joint activities such as lunch, and takes the initiative in academic and social activities in the scholarship group
- participates in professional discussions with colleagues
- has a friendly and positive attitude
Emphasis will be placed on personal and interpersonal qualities.
- exciting and stimulating tasks in a strong international academic environment
- an open and inclusive work environment with dedicated colleagues
- favourable terms in the Norwegian Public Service Pension Fund
- employee benefits
Salary and conditions
As a PhD candidate (code 1017) you are normally paid from gross NOK 532 200 per annum before tax, depending on qualifications and seniority. From the salary, 2% is deducted as a contribution to the Norwegian Public Service Pension Fund.
The period of employment is three years, with the possibility of a fourth year.
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.
