Master’s Thesis Position in Control Engineering and Power Transmission Systems

Aalto University is a new university with over a century of experience. Created from a high-profile merger between three leading universities in Finland – the Helsinki School of Economics, Helsinki University of Technology and the University of Art and Design Helsinki – Aalto University opens up new possibilities for strong multidisciplinary education and research. The university has 20 000 students and a staff of 5 000 including 350 professors.

The open position is located in the School of Electronical Engineering at the departments of Automation and Systems Technology and Electrical Engineering.

Job Description: We are offering a full-time position (6-8 months) for a master’s thesis worker. The master’s thesis work will be carried out as a collaboration project of two research groups in two departments at Aalto School of Electrical Engineering: Department of Automation and Systems Technology (Control Engineering) and Department of Electrical Engineering (Power Transmission Systems). The work is funded by Nordic Energy Research and it is a part of a collaboration project of Nordic universities and transmission system operators called STRONgrid (Smart transmission grid operation and control project ). The research topic of the offered position is related to the development of power oscillation damping control in power transmission systems.

Inter-area electromechanical oscillations are low frequency oscillations, where the generators in different areas oscillate against each other with a frequency of 0.2–1 Hz The oscillations must be damped effectively to maintain secure and stable system operation. Therefore, it is important to analyze the oscillatory behavior of the system in order to understand the system's limits. The power transmission limits may be increased by the installation of stabilizing controls.

In the master’s thesis work, two control strategies will be studied and compared: a local control in each generator and a centralized wide area control. In the local control, the input signal(s) to the controller are measured nearby the controlled device, such as a generator. In a wide area control the input signal(s) are measured over a long distance from different locations in the power system. The goal of the work is to analyze these control strategies and implement them to a power system simulation model.

Requirements: We are looking for a student with a background in control engineering. Knowledge related to electric power systems is not required but considered as an advantage. A reasonable familiarity with simulation packages such as Simulink is expected.

Job Details: The job will start immediately after the recruitment has been completed. The work will take place either in the Department of Automation and Systems Technology or in the Department of Electrical Engineering at School of Electrical Engineering. The guidance team will consist of persons from the research groups of Control Engineering and Power Transmission Systems and the Finnish power transmission system company, Fingrid. The salary will be based on the agency-level agreement of Aalto University.
