Voltage Source Converters (VSCs) have commonly been found in renewable power generations, flexible ac and dc power transmission systems, and energy-efficient drives. The dynamic modeling and control of VSCs are thus critical for stably operating those VSC-based systems. This course devotes to cover the fundamentals and state-of-the-art of the small-signal modeling, stability analysis and controller design for VSCs in both power grid applications and variable speed drives. The main topics include Small-signal models of VSCs Fundamentals of vector control and current control of VSCs Stability of current control with L-/LCL-filtered VSCs Stability impact of grid synchronization and direct voltage control Dynamic models of induction motors and permanent-magnet synchronous motors Fundamentals of sensor-less control of ac drives Active stabilizing techniques for VSC-fed systems


Prior knowledge of power electronics fundamentals, feedback control theory, electrical machines, and three-phase systems is preferred.

Form of evaluation

The participants will work, either individually or in a group of 2 persons, on the exercise designed on the basis of lectures given each day, and then submit a report from the exercises for evaluation. The exercises will be done in MATLAB/SIMULINK with PLECS Blockset.




6000 DKK for PhD students outside of Denmark and 8000 DKK for the Industry.
