THESIS - Dynamic coupling of hydropower units

Background 

The rapidly developing electrical power system with increased dynamics from more wind power has led to a need for increased flexibility and robustness of hydropower electricity production. Traditionally, hydropower plants have been used to regulate the electricity grid frequency but new requirements for dynamic stability have made it difficult for some turbines to qualify for frequency regulation services. It is currently uncertain how quick hydro turbine frequency regulation affects the performance of other units in the same station or river system.

Objective 

The Master Thesis Project includes conducting a literature study of frequency regulation within hydropower and a theoretical investigation of the dynamic effects of frequency regulation to other units in the same power station and local river system. 

The aim of the work is to develop a better understanding of how frequency regulation in individual turbines and hydropower stations influences other nearby turbines and stations that share the same water and how this interaction can be optimized to better provide grid services. 

Our offer 

At Fortum we see a Thesis Project as a good way to get to know you during your study time and for you to learn more about Fortum and how our business is working. A Supervisor will be appointed to support and guide you through the Thesis Project and you will also create a network of people within the Company as well as with other Students doing their Thesis with us.  

For a well performed and approved work, we will provide a taxable lumpsum award. 

This Thesis Project is preferably executed at either of our offices in Stockholm/Solna or Borlänge. 

Your Qualifications 

We believe that you are studying Mechanical Engineering, Electrical Engineering, Engineering Physics or similar, at a Master Programme level. Courses or experience in hydropower are meriting. The Project can be performed in either Swedish or English. 

We expect you to be analytical, energetic and able to work independently. You like challenges and are interested in solving complicated technical problems. 

Interested? 

To apply, register your CV and a personal letter of maximum one page or a Power Point presentation of maximum two slides, in our Recruitment Tool via “Apply now”, latest by 24th November 2024. Applications will be evaluated continuously and an applicant may be on-boarded before this date. 

The personal letter shall include an approach on how you would like to investigate the idea. Mark your application with the reference number HYG-170.
