Synchronization of Lienard-Type Oscillators in Heterogenous Electrical Networks
Motivated by potential applications for power-electronic converters in microgrids, we study the problem of global asymptotic synchronization of Lienard-type nonlinear oscillators in heterogenous LTI electrical networks with series R-L circuits modeling interconnections. By heterog...

Hierarchical Data-Driven Protection for Microgrid with 100% Renewable Penetration: Preprint
The accurate detection and isolation of faults is critical for the reliable operation of microgrids (MGs). Traditional protection approaches are even more challenged for 100% renewable MGs because inverter-based resources (IBRs) are the only sources for fault current which are usu...
