Dr. A. (Aleksandra) Lekic



Aleksandra is involved in the following projects:
  • InterOPERA, as a co-principal investigator
  • Harmony, as a principal investigator
  • SAFE-GRID, NWO Veni individual project
  • SUNRISE, as a principal investigator from TU Delft and WP3 lead
  • EASY-RES, as task 6.4 lead - finished project



Aleksandra's research topics are related to the circuit theory, control, and stability analysis of nonlinear switching power converters and hybrid power systems employing power electronics. She has worked on circuit theory concepts applied to multiport power system analysis, with a special focus on HVDC systems; and harmonic stability assessment of the hybrid power systems consisting of the passive and active components: impedance-based MMC and other VSC modeling. Also, she has developed multiple nonlinear controlling algorithms relying on the Lyapunov theory, and model predictive control methods used for stable and efficient control of switching converters and systems consisting of renewable sources and power converters. 
Her research team has contributed with open source solutions for:
  1. RSCAD/RTDS based entirely scripted futuristic North-Sea energy hub models: https://github.com/control-protection-grids-tudelft/HVDC-RTDS-models
  2. Automatic nonlinear MPC solution for the DC-DC converters: https://github.com/kul-optec/dc_dc_simulator


Aleksandra received B.S., M.S., and Ph.D. degrees in electrical engineering from the School of Electrical Engineering, University of Belgrade, Belgrade, Serbia, in 2012, 2013, and 2017, respectively.  Between 2012 and 2018 she has been a Teaching Assistant with the School of Electrical Engineering, University of Belgrade, and an Assistant Professor from 2018 to 2019. In 2019 she worked as a Postdoctoral Researcher at the Department of Electrical Engineering ESAT – ELECTA, KU Leuven, and in the Institute EnergyVille, Genk, Belgium. Since January 2020, Aleksandra works as an Assistant Professor at TU Delft, Faculty of Electrical Engineering, Mathematics and Computer Science. 
Aleksandra leads a team of researchers (four Ph.D. and five postdoctoral researchers) specializing in the Control of HVDC/AC power systems. She is an Associate Editor in the International Journal of Electrical Power & Energy Systems, Elsevier, and in the Electrical Engineering, Springer. Aleksandra represents TU Delft in the General Assembly in the CRESYM organization, committed to open-source software development for the electrical grids.
