Project description

Integreringen av förnybar energi i elnätet ökar. En viktig skillnad för nätanslutningen av traditionell elkraftproduktion som kärnkraft och vattenkraft, som dominerar det svenska nätet, och förnybar energi, är att generatorn kan kopplas synkront till nätet. För intermittenta energikällor, såsom havs-, vind- och solenergi, måste anslutningen göras med ett mellansteg med kraftomvandlare. Genom att ansluta till nätet med kraftomvandlare överförs inte trögheten från generatorn till nätet, vilket leder till ett elnät som är mer känsligt för skillnader i producerad och förbrukad effekt, vilket orsakar frekvensfluktuationer.

The division has a dedicated lab for power electronics research, as well as several experimental stations with in-house made power converters. This project aims to design, develop and test power converters for connecting several generators for marine current power to the grid. The project has access to simulation software, the experimental lab, and the experimental site with a marine current power turbine in Söderfors, Sweden.

Some suggested topics, depending on the interest of the candidate:

• Multilevel converters
• Grid connection topologies
• Control of generators

Duties 

• Lab work including building and preparing power electronics equipment.
• Write scientific papers and publish in relevant scientific journals.
• Present the research orally at relevant international conferences.
• Teaching (for example tutorials and labs) and other departmental duties of no more than 20%.

Requirements

• The applicant must hold a master degree in, engineering physics, energy systems, electrical engineering, or a similar field.
• Knowledge of modelling tools such as Matlab/Simulink/LT Spice.
• Very good oral and written proficiency in English and swedish.
• We will put an emphasise in your personal qualities such as that you show independence, that you are goal- and result oriented, have good cooperation skills and are good at oral communication.

Merits

• Lab experience with measurement and control of power systems with power electronics.
• Experience with LabVIEW and cRIO.
• Simulations of power systems in Simulink or similar.
• Work in power systems or power electronics.
