The Opportunity

We are looking for a master thesis student at our dynamic control design department, who would like to join our multinational organization with lots of development opportunities. Our team is dedicated to creating a future where innovative digital technology brings cleaner energy to people around the world. If this opportunity excites you, we encourage you to apply!

How you will make an impact

• You will create a simple power systems model in Matlab/Simulink with a Thevenin AC network, the converter modelled as a voltage source and fixed DC voltage at the DC side for different operating modes.
• Implement generic models in Matlab/Simulink for grid forming control of VSC HVDC, with and without embedded current control.
• Implement a generic model for grid following control of VSC HVDC.
• You will perform linearization of the developed model to obtain a linear state space model.
• You will verify time domain behaviour by comparing simulation results from nonlinear and linearized models.
• Use the linearized model to investigate how system stability is affected by different control system parameters and compare the different control principles, for example eigen value analysis, participation factors.

• Pursuing a Master of Science degree.
• You will create a generic VSC model that can be linearized in Matlab/Simulink. It is proposed that the study is done in the framework of a 20-week master thesis project.
• You have knowledge in MATLAB extensively used within HVDC system studies due to its capacity to perform complex analysis within the same environment.
• You will create a simplified model in Matlab/Simulink that permits to perform fast small signal analysis of the control system and draw general conclusions.
• This can also be seen as a feasibility study to evaluate the capacity of Matlab/Simulink for future development and perform benchmarking between other tools that have linearization capabilities (e.g. Dymola, Power Factory).
