On the small-signal stability and impedance passivation in power electronics dominated future electrical grids.  
The presentation will describe some recent control-oriented research issues concerning small-signal stability and dynamic interaction in future electrical grids dominated by power electronics converters. The presentation will focus on small-signal stability based on impedances, self-tuning and stability monitoring, impedance specifications, unterminated modeling, and the impact of high-performance oversampled current/voltage control. Different approaches to enable impedance passivation, including unterminated converter modeling, will be outlined. Examples will cover a range of different scenarios, including small lab-scale microgrids, multi-port converters, soft-open point applications, and offshore wind power plants.
