This is why we warmly encourage qualified candidates from all backgrounds to join our community.

We are seeking a doctoral researcher to join the Department of Electrical Engineering and Automation at Aalto University, Finland.

You will work in the Research Group of Power Transmission Systems on a research project investigating interactions between the power grid and turbine-generators, with Olkiluoto 3 nuclear power plant as the main case study. Olkiluoto 3 is one of the largest nuclear power units in the world. The goal is to improve the understanding, monitoring and mitigation of subsynchronous resonance and oscillations caused by grid disturbances. You will work in collaboration with companies, such as TVO and Fingrid.

Research focus

Monitoring and data analysis: Apply and develop methods to estimate torsional oscillation frequencies, damping and amplitudes from phasor measurement unit (PMU) data. Analyse long-term measurements to identify how these properties depend on grid operating conditions.

Modelling and mitigation: Develop and validate simulation models of grid-generator interactions, particularly in power systems with a high share of power converters. Assess oscillation and resonance risks associated with converter interactions and forced oscillations from large loads, such as data centres. Evaluate strategies to prevent or damp harmful oscillations.
